to recover the heavier sulphides from their silver-gold ore before pas- 
sing it through their counter-current decantation cyanide system. This 
relieves the system of the heavy cyanide loss that would be caused by 
the excessive sulphides found in depth in the mine, and these Concen- 
trators give a very high grade concentrate that can be shipped econom- 
ically, even though the mine is over 50 miles from the railroad. 

These machines were selected only after tests that proved their ability 
to meet these difficult requirements, and after other makes had failed. 

170 tons of Dorr Classifier-overflow material per 24 hours

^ 



THE MOST PRACTICAL FINE 
SCREEN ON THE MARKET 

Every mill man knows of the many advantages of fine screening in the 
different prosesses of ore dressing. 

By fine screening, a positive separation of the coarse sand from the fine 
sand is effected. When the coarse sand is to be concentrated on tables, jigs 
or other machines, the screened product is positively free from all that fine 
material that cannot be saved on a machine adjusted for the handling of coarse 
material; or, when the coarse sind is to be reground before being subjected 
to further metallurgical treatment, the fine screening reduces the load on 
the grinding machines. Fine screening, therefore, greatly increases tl e 
efficiency of milling machinery. 

The Bunker Hill Screen has proven itself exceptionally well adapted to 
fine screening. 

The large capacity of the Bunker Hill, its wonderful simplicity, the 
small mill-head and floor space required and its light weight are all proper- 
ties that make possible its adaption anywhere in a mill. The rapidly in- 
creasing demand for Bunker Hill is the best indication of its usefulness in 
ore dressing.

For TROMMELS 



Conditions governing the operation of trommels im- 
pose the severest duty upon the screen. The ore is 
either dumped or fed through a chute in the trommel, 
which revolves and carries the particles upward and 
forward until the fine material has passed through the 
meshes of the screen, and the reject discharged at the 
other end. Thus the screen is subject to wear by 
both attrition and impact, a severe test upon its stamina. 



PERFECT 

Double-Crimped Woven -Wire Screens 

are exceptionally strong and stiff 

The double-crimping process forms the wires 
into a series of flat arches, with the ends buttressed 
against one another, and the arch is the strongest 
form of structure known to engineering. Then 
again, this same process of double-crimping gives 
a higher percentage of effective screening area, a 
condition equally desirable.

NO GRADES TOO STEEP FOR 
THE DUPLEX 4-WHEEL DRIVE 

STURDY and dependable, with irresistible reserve power, Duplex 
4-Wheel Drive Trucks begin their notable haulage tasks where 
other types of commercial vehicles leave off. Exclusive application of. 
the Duplex 4-Wheel Drive principle makes it possible for Duplex 
trucks to haul capacity loads under conditions that prevent the opera- 
tion of any other type of heavy haulage vehicles. 

No grades are too steep ; no roads too 
snow-embanked ; no sand or mud too deep 
for the Duplex — the motor truck that is 
equal to any emergency. 

Built for year- 'round service Duplex 
Trucks are on the job spring and summer, 
fall and winter — 12 months of every year — 
performing satisfactorily under most ad- 
verse road conditions. They are opening up 
new territory to motor truck transportation 
— hauling raw materials and finished prod- 



ucts overland from city to city — giving 
never-faltering service. 

. Duplex Trucks are built especially for 
mine operators, contractors, road builders, 
manufacturers and jobbers — and are de-- 
livering capacitj^ loads at lowest ton-mile 
costs. Let us send you data showing how 
profitably the Duplex is solving haulage 
problems in your line of business. Write 
for our catalog and the heavy haulers' 
magazine, "Duplex Doings", issued in the 
interest of better transportation methods.

Continuous Vacuum Filtration 

It is not necessary to buy an addi- 
tional filter when increasing the 
capacity of your mill if you are 
using the 

American Continuous Filter 



iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiniiiiiiiiiii 




The disc and separate hopper constructions 
permit increasing the filter area by simply 
adding another shaft section, with discs and 
extra pans, instead of buying a whole new 
unit. 

Any unit may be increased or decreased as 
to capacity with small expense and in a very 
short time. 

This makes for a decided saving in both 
money and time to the operator. 



It weighs less; it requires less power; it re- 
quires le.-s floor space; and it has a greater 
capacity per square foot of filter area than 
any other continuous vacuum filter on the 
market. These are substantiated facts. 

We maintain a staff of engineers and 
testing laboratories and will be glad to tell 
you just what the American Continuous 
Vacuum Filter can do toward increasing 
the efficieney of your mill.

These bearings can be applied to cars when de-

By their use the draw-bar pull for any load is 
reduced about 60 per cent; they last for an in- 
definite period, and require no care beyond 
lubrication.

To Users of the Callow Pneumatic 

Flotation-Cell 



Users of the Callow Cell are naturally interested in knowing how the decision 
of the United States Circuit Court of Appeals for the Third District, in the Miami 
case, will affect their interests. 

As we understand the prevailing opinion of Judge Woolley in the Miami case, 
he has interpreted the Supreme Court decision in the Hyde case as meaning that 
"invention resides not alone in the critical proportion of oil, but also in air and 
agitation", and again, "in the co-action of the critical proportion of oil and air 
affected by 'an agitation greater than, and different from that which had been 
resorted to before', resulting in a froth concentrate of economical value", and 
further, that the Supreme Court did not limit the patent to "agitation by 
mechanical means", but to agitation of a violent and persistent kind; "it mixes 
the oil with the metal of the ore. This is old. Then, by its greater intensity 
and longer duration, it stirs the pulp into a froth". 

Thus, this decision of the Third Circuit Court of Appeals has a most impor- 
tant bearing upon the art, because it holds that the mixing of the oil with the 
mineral is old, but it leaves open the use of oil in connection with aeration-cells. 
Meanwhile the idea of a 'critical' proportion of oil has been disproved by practice 
in several mills within a short time after it was promulgated. 

Judge Woolley says further, concerning the Callow Cell: "Aeration is 
direct, and is not the result of or -caused by agitation. On the contrary, agita- 
tion results from aeration and such agitation, though present in some measure, 
is not even approximately of the violence and duration of the agitation of the 
patent. The operation in the Callow Cell certainly possesses these distinguishing 
features from operation of the process where aeration is caused by agitation". 

The Court further confirms this important dictum by saying : "If the only 
agitation to which the pulp was subjected (after such agitation as in the prior 
art was necessary to mix the oil and ore) was the agitation of the Callow 
Cells, we would not say that that agitation amounted to or was the equivalent 
of the violent agitation of the patent disclosure and constituted infringement". 

Apparently users of the Callow Cell may feel assured they do not infringe the 
method of agitation described in U. S. Patent No. 835,120 (less than \% oil), No. 
962,678 (soluble frothing agents), No. 1,099,699 (phenol or cresol in the cold 
without acid) since all three of the patents are of the same process, dependent 
upon a certain degree of violence and length of agitation and the production of the 
same characteristic froth, as set forth in their claims.

They are so fine, so different, in 
the economical use of air, atten-

you will wonder why you did 
without them so long. 

You need every minute oftftime, 
that you save through the high 
drilling speed of these machines, 
to get the additional drill hole 
footage you are after. It means 
increased production. If pos- 
sible, you want double the foot-

duce that labor item, the one 
biggest item in the cost of rock 
drilling operations. 

Leyner-Ingersoll Water Drills

WHITE TRUCK 





MINE TO RAILROAD 

White Trucks Supply This Difficult Link in Transportation 

ORES necessary for making steel, iron, copper, zinc and lead are vital 
factors in winning the war. Every source is worked to the limit. 
After they are mined there is still the difficult task of rapid transpor- 
tation to be met. In scores of cases this transport problem is being most 
satisfactorily handled between the mines and railroads with speedy, 
efficient, durable White Trucks. 

Six White Trucks owned by B. H. Maddox & Company are moving 
the output of magnesite from the White Rock Mines to the railroad 
at Rutherford, Cal. — a distance of twenty miles. These trucks are 
operated 18 hours a day over mountain roads — each truck makes three 
round trips or a total of 120 miles a day. Arriving at Rutherford the 
ore is forwarded by fast freight to its destination. 

Despite the efficiency of production at the mines or the rapidity of 
transportation by rail, the amount of ore delivered for final use depends 
upon the means of moving it through the mountains from mines to 
railroad.

Detail of Howe Roof-Truss 

Mine managers and engineers are frequently called upon to design and build surface-structures at 
mines, ore-bins, mills, head-frames, trestles, flumes, and other structures requiring heavy timber-fram- 
ing. It is desirable that the structures be as simple in design as possible, while meeting the demand for 
safety and efficiency. There is a very common lack of the appreciation of the strength of timber-struc- 
tures properly framed, and this results in much unnecessary expense and waste of materials by building 
a structure in which the timbers are of far greater ske than the condition demands. By knowing how, 
the designer builds neither too expensively, nor is his structure weak. It is for the determination of 
these questions that 'Timber Framing' will be of great value.

A Special Opportunity for Service 
A Call for Mining Men 

Uncle Sam wants men of your ability and acquaintance to serve 
or help him find superintendents, foremen, and skilled workmen, 
experienced in mine and quarry operations. 

Any man between eighteen and forty years of age, who has not 
actually been called for service in the draft, may enlist in the 27th 
or 28th regiments of Engineers if his experience qualifies him and 
he can pass physically. Both regiments will be made up entirely of 
men who enlist voluntarily. 

All mining operations in the fighting zone, such as the construction 
of tunnels, galleries, bomb proofs, special trenches and the like, will be 
directed by the Twenty-Seventh Engineers. These operations involve a 
variety of highly specialized work, requiring much machinery and equip- 
ment, most of which has been developed at the front in the last two years. 

No other branch of the service offers men of the right experi- 
ence so good an opportunity to make their efforts count. 

The Twenty-Eighth Engineers will superintend and conduct quarry 
operations. Crushed stone is required in enormous quantities in war 
operations for the construction and maintenance of highways and rail- 
ways, and numerous other purposes. American methods and the best 
types of American machinery will be used for this purpose. 

AMERICA presents to you this opportunity to enlist or help to enlist 
skilled and experienced men in all branches of mining and quarrying for 
service in these two regiments. 

Enlistment can be made through your nearest recruiting office or by 
mail upon application to the address below. Written applications must 
give name, address, occupation, position, experience, schooling, etc. 

Address Application to 

Commanding Officer, 27th or 28th Engineers

For Better Service in 
Mechanical Rubber Goods 




THE United States Rubber Company, on January 1st, 
1918, inaugurates an improved method of marketing in 
its Mechanical Goods Division. 

This division includes Rubber Belting, Packing, Fire, 
Steam, Water, Garden and all other kinds of hose; Rubber 
Tiling, Mats, Matting, Jar Rings, Toys, Plumbers Supplies; 
Rubber Tape, Soles, Heels; Fibre Soles and hundreds of 
other rubber items. 

Heretofore these goods have been marketed through sub- 
sidiary companies that for years have served all classes of 
industries, railroads, etc. These subsidiaries include 

Revere Rubber Co. Mechanical Rubber Co., Chicago 

Peerless Rubber Mfg. Co. Sawyer Belting Co. 

Mechanical Rubber Co., Cleveland India Rubber Co. 

Eureka Fire Hose Mfg. Co. 

This plan will centralize the distribution of all these companies in 
one organization having branches and agents all over the country. This 
means quicker and better service everywhere for users of mechanical 
rubber goods. 

The subsidiaries will continue to manufacture the brands such as 
Rainbow Packing, Four Ace Belting, Giant Hose, etc., etc., for which 
they are famous. The same high standard of quality and workmanship 
will be maintained. In addition the great seal of the United States 
Rubber Company, the hall mark of quality and value in rubber goods 
will identify these goods. 

The assembling of all these well known brands in one selling organ- 
ization makes the most complete line of mechanical rubber goods in the 
world. With distributors everywhere and factories in the large centers 
east and west we assure our customers the maximum in service and quality.

THE MODEL 8 

"WAUGH" 

SHARPENER 




"Waugh" Sharpener on the U. S. Reclamation Service Work at 
Kimrock, Wash. 



The maximum efficiency of a rock drill 
is dependent upon the use of correctly 
formed bits and shanks. In modern prac- 
tice hand-sharpening is too slow to be 
economical. 

The Model 8 "Waugh" Sharpener not 
only produces properly worked bits and 
shanks, of perfect gauge and length, but it 
also makes them in the shortest possible 
time with the minimum consumption of 
air. 

In addition to using less air at equal 
pressures than other machines, it will also 
operate effectively on lower pressures than 
are required by machines of similar 
capacity.

The first successful concentrating table was a 
WILFLEY. TWENTY THOUSAND have since 
been sent to mining districts all over the world. 

The WILFLEY does not keep up with the develop- 
ment of ore-dressing — it keeps ahead of it. 

Our engineers and trained, practical work- 
ers are always in the field. When a new 
condition arises, these men know of it, 
study it, and make the WILFLEY meet it . 

Because of their rugged construction the 
cost of maintaining WILFLEY TABLES 
is very low. 

Capacity in tonnage handled and capacity 
in high percentage of extraction are the 
features which make for the success or 
failure of a concentrating plant. \! 

The WILFLEY has constantly kept a step 
ahead of all other concentrators in the de- 




velopment of new features to handle larger tonnages 
and give cleaner separation. 

Our No. 1623 and No. 10 riffles are but two of the 
many famous riffling systems which have been de- 
veloped in our shops and which give the WILFLEY 
a capacity in excess of 100 tons daily un- 
der favorable conditions. We have many 
other riffling systems to meet special con- 
ditions. 

Remember that the WILFLEY TABLE 
has greater capacity than other concen- 
trators, and because of its rugged con- 
struction and simple design the cost of 
upkeep is less. 

Submit your concentrating problem to our 
engineers who will tell you which 
WILFLEY will best meet your conditions. 

Since there 's no obligation, why not write

G-E Complete Electrical Equipment 

for Cranes Assures Speed with Safety 



G-E engineers have studied crane require- 
ments and designed electrical apparatus to 
meet known operating conditions. Every 
requirement for stopping or starting, and the 
entire operating cycle is fully met by specially 
designed apparatus. 

Motors 

Interpole motors, capable of standing heavy over- 
loads, are manufactured in any speed or horse- 
power needed. These motors have split frames and 
large handholes for accessibility, and can be dis- 
assembled without disturbing back gearing. 

Brakes 

G-E crane motors are furnished with automatic 
solenoid brakes which work without jar or shock 
and make automatic compensation for brake shoe 
wear. Brake shoes made of metallized asbestos 
compound give a high co-efficient of friction with 
but little wear. 



Resistors and Protective Panels 

The G-E standard for crane equipment is to sup- 
ply all resistor sections of uniform size, which re- 
duces the number of spare parts needed to a mini- 
mum. The design of the cast iron grid resistance 
units is such as to avoid the danger of short cir- 
cuits by vibration and double insulation protec- 
tion against grounding is provided. 
Protective devices are furnished in small panel 
units which can be attached in any convenient 
place. A push knob on master panel opens line in 
an emergency, and overload protection is afforded 
at all times. 

Controllers 

Horizontal or vertical handle controllers are fur- 
nished which are absolutely reliable and very ac- 
cessible. They are equipped with magnetic blow- 
outs, arc chute protecting covers, and many refine- 
ments which twenty years of controller building 
suggested. 

Your inquiry for complete electrical crane equip- 
ment is solicited.

rpHAT grand old mine, the St. John del Key, in Brazil, 
-*- is still vigorous. It is the deepest gold mine in the 
world, the lowest level being 6066 ft. below the surface. 
Last year this venerable enterprise yielded a profit of 
$335,000, from the treatment of 94,300 tons, averaging 
$12.50 per ton. 

TVTERO fiddled while Rome was burning and lives in 
•*■ ' history as the type of the heedless spectator of a 
great event. So today, while civilization is sent to the 
shambles and nations fight- for existence, there are people 
that enjoy dog shows and cat shows, and there are news- 
papers that think to find interesting copy in such silly 
performances. 

/~^ OLD production in South Africa is suffering from 
^-^ labor shortage. The output of the Rand for 1917 
is about $1,000,000 less than in 1916, Rhodesia and Aus- 
tralia show a decided decrease, while India and "West 
Africa are holding their own fairly well. On the whole, 
despite the difficulties created by the "War, the output of 
gold in the British dominions is being maintained at a 
high level, but no new and important discoveries have 
been made of late. 



DIVIDENDS paid by copper companies during 1917 
are estimated at $179,000,000 as against $157,000,- 
000 in 1916, although the average price of copper was 
slightly lower. The fixation of the price at 23| cents 
caused many reductions in dividends during the last 
quarter of the year. The Utah Copper heads the list 
with a disbursement of $23,555,105 to its shareholders, 
as against $19,493,880 in 1916. The Anaconda paid 
$19,815,625, and the Kennecott $15,832,194. Among 
the young producers the Inspiration paid $9,751,228, 
the Miami $6,537,360, and the United Verde Extension 
$2,992,500. The prospect for 1918 is prosperity, but 
with less lavish distribution of profit. 



A NOTHER highly successful amateur golf tourna- 
-'"*- ment is reported from Del Monte. Any man that 
has the spare time and the physical fitness to play 
championship golf ought to be serving in the Army or 
Navy. Such public exhibitions of detachment from the 
"War justify the statement, made by the editor of the 
'National Service' magazine, that "we are fighting, com- 



pared with the other great fighters, approximately a 
20% war, in the sense that compared with them we are 
using but 20% of available resources." By such slack- 
ing we face the danger of our failure to end the War, 
the possibility of such indecisive fighting as will prolong 
the calamity and increase needlessly our sacrifice of men 
and material. Let us put aside dog-shows, symphony 
concerts, and golf tournaments until we have seen this 
thing through. 

ON another page we publish an article concerning in- 
dustrial conditions by Mr. Charles T. Hutchinson, 
the manager of the business department of this paper. 
It is timely and written in a style that will be refresh- 
ing to the readers of technical descriptions. Mr. 
Hutchinson dwells upon the function of advertising and 
the purpose of such a periodical as ours, which, of course, 
is to furnish reading matter to those that buy, or direct 
the buying, of the manufacturers advertised through our 
medium of publicity. Fortunately those whom we aim 
to interest are more than commercial agents, they hap- 
pen to be engineers and captains of industry, constitut- 
ing a public whom any editor might be glad to address. 
The realization of that fact harmonizes the commercial 
and the idealistic elements into a task that lacks neither 
interest nor usefulness. 



T> UTTE has had an eventful year, as is shown in the 
■■-' review by Mr. Ben P. Evans appearing in this issue. 
Besides its copper, with which gold and silver are ex- 
tracted as by-praducts, this district is now yielding man- 
ganese, so urgently needed in steel-making. "We publish 
a short article on this phase of the local industry. "We 
note with pleasure that the general search for manganese 
is proving successful, for the U. S. Geological Survey 
reports that during the first nine months of 1917 the 
production of first-class ore was 70,225 tons, by 88 
operators, as against 26,997 tons, by 55 operators, during 
the whole of 1916. It is estimated that the total output 
for 1917 will be 122,275 tons, and that in the current 
year shipments may increase to 200,000 tons. The States 
prominent in this good work are Montana, Arizona, Cali- 
fornia, Utah, and Nevada. In our issue of November 17 
we gave details concerning the manganese deposits of 
Philipsburg, Montana, and in that of November 24 simi-

lar notes concerning the manganese resources of Lead- 
ville, Colorado. 

rPHAT the lack of developed mines in the Argentine 
•*- republic is due to ill-conceived mining laws that fail 
to stimulate prospecting and exploitation is a statement 
of great significance coming, as it does, from Mr. Horace 
V. Winehell, one of the world's foremost economic geolo- 
gists. In his letter on 'Mining Laws for Eussia," pub- 
lished in this issue, he affirms that the eastern slope of 
the Andes, lying within Argentine territory, contains 
mineral resources as great as those in Chile. The liberal 
policy toward mines on the part of Chile is credited with 
being the chief cause for the great expansion that has 
resulted in stimulating her output of mineral products 
until they now reach a value of $140,000,000 per year. 
The contrast between this and the paltry sum of 
$300,000, which represents the yearly total of the Ar- 
gentine output, should arouse to action the president of 
that republic, Hipolito Irigoyen, a man of practical 
sense, whatever we may think of his politics. He is not 
likely to overlook an opportunity for the improvement 
of his country when the proper course is made con- 
vincingly clear to him. For the sake of any who may be 
inclined to let the bad impressions created by Mexico 
influence their opinions of her well-behaved sisters in 
South America, we may point out that the Argentine 
government, to all appearances, has become as stable as 
our own. That involves progress in the arts and in the 
making of rational laws. The criticism offered by Mr. 
Winehell does not mean that the Argentine government 
is illiberal and restrictive in the sense applicable to re- 
cent Mexican legislation; it means merely that a great 
pastoral and agricultural people, blessed with rich pam- 
pas lying close to the sea, while their minerals are hidden 
in the remote western mountains, necessarily developed 
first the accessible riches, and that they have not awak- 
ened to the reality of the opportunities for the production 
of metals. The same course of tardy development charac- 
terized the United States. Prior to 1866 there was no 
Federal mining law on our statute books, and the one 
adopted in that year was slipped through Congress as a 
rider on a ditch-law. It is interesting to be assured, by 
so trustworthy an authority as Mr. Winehell, of the 
existence of these virgin resources in a country that has 
passed through the revolutionary measles and whooping- 
cough to mature healthiness. Favorable legislation will 
unlock the Argentine treasures in due season. 

~D USSIA will need a stable government before any 
■*-*• mining laws can be effective. Mr. Winehell 's recom- 
mendations were made when the Kerensky administra- 
tion was in the saddle and, it was hoped, so firmly as to 
be able to ride the storm of revolution. We have not 
always agreed with Mr. Winehell as to the advisability 
or otherwise of changing our own mining laws, but that 
does not prove necessarily that his ideas are wrong. 
What he says to the Ministry of Commerce at Petrograd 
concerning the American law of mining is well expressed 



and to the point. His suggestions are wise, particularly 
as to the need for simplicity and uniformity in the pro- 
posed regulations; also for the withholding of mineral 
land from persons or corporations unable or unwilling to 
develop them, that is, to discourage the speculative hold- 
ing, or 'shepherding' of claims, as they call it in Aus- 
tralia. Likewise he places emphasis on the desirability 
of free markets and the absence of vexatious restrictions 
to operation. He refers to the regulation compelling 
foreign companies to employ Russian engineers as man- 
agers. This has proved a hindrance, rather than a help, 
in most cases, causing a duplication and conflict of man- 
agement not at all favorable to profitable enterprise. 
It would be better to leave the engagement of Russian 
engineers to the discretion of the operating companies, 
which would find it useful, in more senses than one, to 
employ some of the many capable technical men now 
available among the Russians themselves, but the delega- 
tion of supreme local authority to a person nominated by 
anybody but the board of directors only works for 
trouble. This has been one of the drawbacks to operat- 
ing in Russia, and we hope to see it adjusted in a friendly 
manner for the benefit of all concerned. Meanwhile the 
many capitalists and engineers interested in Russian 
mining, and anxious to participate in the exploitation of 
Russian mineral resources, must possess their souls in 
patience. No business is possible until sane government 
has been restored. 



ON another page we publish a review of operations 
during the fourth quarter of the past year in the 
zinc-lead region that extends over parts of Kansas, Okla- 
homa, and Missouri, to which we have ventured to give 
the name of Komspelter. Whether this convenient name 
will prove acceptable to those most nearly concerned, we 
do not know yet. It will be noted that the mining of 
zinc deposits, containing lead in proportions varying 
from a mere impurity to an important by-product, has 
spread south-westward from Joplin to Picher, and then 
nearly northward to Crestline, transgressing the borders 
of three States. Our correspondent, Mr. Otto Ruhl, has 
long been identified with the Joplin mining industry 
and is especially qualified to write on the important de- 
velopments in that part of the country. He will not be 
offended if we mention the fact that we had to correct 
his use of the term 'ore' in order not to confuse those 
of our readers that are unfamiliar with the local ter- 
minology. It is the custom at Joplin and its tributary 
mining communities to use the word 'ore' to signify 
'concentrate,' although the same word is also applied to 
mill-feed or crude ore as it comes from the mine. The 
significant quotation on the local market is the price for 
'ore,' which means a concentrate containing 60% zinc. 
Other local terms include 'dirt' for mill-feed and 'chats' 
for a jig-product that needs re-grinding to liberate par- 
ticles of blende. To these there is less objection because 
at least they will not be taken to signify something 
quite different, but to speak of a concentrate as 'ore' is 



January 5. 1918 



MINING and Scientific PRESS 



about as silly as the custom, iu Gilpin county, Colorado, 
of giving the nam.' of 'tailings' to the pyritic concen- 
trate sent from the mill to the Bmelter, or the Lake Su- 
perior habit lit' calling copper ore 'rock.' The use of 
such self-contradictory terms may not confuse residents 
in the district, but it makes for confusion when they 
undertake to give information to those outside, and it is 
objectionable in a broadly basic way because it stultifies 
the language of technology. Now that the zinc region — 
not 'district' — of Komspelter is attracting the attention 
of operators and engineers all over the country, it would 
be' well to use terms that everybody will understand. 

Peace Talk 

The new year opens with talk of peace sufficiently 
serious to test the morale of the Allies. The idea of 
peace is heavenly. None but a criminal lunatic would 
wish to prolong the War by one day, provided the pur- 
pose of our fighting were fulfilled. That proviso is the 
crux of the matter. Our purpose is to check the military 
aggression of a government and a people that have gone 
mad in an intensive effort to dominate the world and 
that, in making the effort, have reverted to methods of 
warfare that shame civilization. We fight to restore the 
world to sanity and orderly living; that can be assured 
only when the aggressor is defeated and so hurt by his 
attempt that he never will be able to make another effort 
of the same kind. This War is a pitiful tragedy, but 
there is a worse possible, namely, that the War shall 
have been in vain, that thousands of young lives shall 
have been sacrificed only to give Germany an interval 
of recuperation for another preparation before she tries 
again to do what she nearly succeeded in doing the first 
time. There must be no second time. The three years 
of the present struggle have seen the invention and de- 
velopment of death-dealing instruments and methods at 
a rate so rapid as to indicate that if the Prussian ma- 
chine were granted twenty years of peace for a second 
preparation it could fashion weapons of war that would 
simply blight the earth like a collision with a comet. 
The present calamity must be the means of preventing a 
greater catastrophe. If we endure the horrors of this 
war, with all its calls for sacrifice of life and happiness, 
if we face a continuance of the bitter struggle, it is with 
the determined purpose that this shall be the last of 
such wars. From the achievement of that purpose we 
shall not be diverted by the poisonous gas of German 
propaganda nor by the delirious drivel of the Russian 
anarchists. The horror of war is impressed upon us; 
we want to end it and to make the guilty breaker of the 
peace so sorry that he too will be deterred from another 
outbreak. Those that have seen the shambles of the 
battlefield and even those that have read the realistic 
descriptions, particularly by French writers, will be in 
agreement that to say that war is inevitable is to utter 
a blasphemy against the human spirit. It shall not be 
inevitable ; it must be made impossible. 



The Affairs of the Institute 



An amendment to the constitution of the American 
Institute of Mining Engineers, with a view to a closer 
definition of the qualifications for membership, has been 
proposed and is now to be the subject of a vote. It has 
long been felt that the Institute suffered from including 
a number of persons to whom the terms 'engineer,' 
'metallurgist,' or 'geologist' were not correctly appli- 
cable. This injured the status of the organization and 
diminished its professional solidarity. Therefore the 
proposed restrictions, all reasonable and moderate, will 
be welcomed. Besides restricting the election to member- 
ship it is proposed to create a class of 'associates,' to be 
qualified by "interest in, or connection with, mining, 
geology, metallurgy, or chemistry." This, at first sight, 
may seem to be so vague as to perpetuate the worst fea- 
tures of the nondescript membership to correct which the 
latest constitutional amendment has been proposed. The 
natural fear of a loyal member of the Institute would be 
that this ' associateship ' may open the doors to non-pro- 
fessional persons without technical training and allied 
rather to the promotion of mining schemes than to the 
operation of mines. We understand, however, that this 
danger has not been overlooked, and that ample protec- 
tion against it is assured by the scrutiny to which every 
candidate's name is exposed by the Committee on Mem- 
bership, a committee that is doing yeoman service. The 
aim is to make the Institute thoroughly representative 
of all the respectable and worthy elements in the diverse 
personnel of the mining industry and yet to restrict full 
membership to those taking a responsible part in its 
technical work. This it is expected to accomplish satis- 
factorily by having both 'associates' and 'members.' 
During the last five years the additions to membership 
have been 433, 921, 553, 750, and 1005, the last figure, 
however, not including any elected after December 15, 
1917. Thus 3662 have joined the Institute in the five 
years, proving the vitality of the organization and the 
energy of the Membership Committee, the chairman of 
which is our former associate, Mr. Thomas T. Read. The 
big gain has been made, with few exceptions, without 
lowering the standard of past membership. Nor do we 
see any immediate danger of lowering that average, even 
after the class of 'associates' has been created, because as 
much care will be taken in electing the latter as was taken 
formerly — say, ten years ago — in the election to full 
membership. The only danger we can see, as a conse- 
quence of a big addition of names, is that of strain- 
ing the finances of the Institute by the publication 
of papers and volumes that cost more than the annual 
dues. Less quantity and better quality, a smaller mass 
of material and closer editing, are needed ; and these we 
shall expect now that Mr. E. K. Judd has been appointed 
editor of the Transactions. On the whole, even a some- 
what detached critic must allow that the management of 
the Institute during recent years has been such as to 
inspire confidence.

A Nationalized Railway System 

President Wilson has followed the recommendation 
made by the Federal Trade Commission last June in 
taking the railroads under Government control. The 
suggestion at that time was regarded in some quarters, 
particularly in railroad quarters, as premature. No 
careful observer could fail to be struck with the fact 
that a great and peculiar hush fell upon the daily press 
of America so far as this topic was concerned immedi- 
ately after the printing of the initial dispatch, which 
said simply that the Federal Trade Commission had 
formally advised Congress that the transportation sys- 
tems of the country, by rail and by water, should be 
"pooled and operated on Government account, under 
the President, . . . as a unit, the owning corporations 
being paid a just and fair compensation." It will be 
seen how literally the President has carried out the 
plan advocated by this competent Commission to whom 
it had become clear, after less than three months of con- 
fusion following the declaration of war, that the com- 
mon carriers, as then constituted, were unable to cope 
with the national crisis. The succeeding six months have 
added force to that conclusion. The nation has lost 
time in military preparation through lack of co-ordina- 
tion in the transportation service, and the people at 
large have suffered extreme inconvenience and enormous 
increases in the costs of doing business over and above 
the rising prices produced by other economic difficulties. 
While efficiency would have been gained by prompt 
action last June, it must be conceded that the trial which 
is now to be made of Government administration of the 
railroads will meet with less hostile criticism in conse- 
quence of the opportunity given by the President to test 
the ability of the railroad managers to meet the crisis by 
themselves. Furthermore, Government aid was afforded 
them through a committee of practical railroad men 
whose purpose was to facilitate an effective co-operation 
under the system of private ownership and control, but 
in the end it became apparent to the whole country that 
the net result had been failure. The public therefore 
accepts the decision of the President with feelings of re- 
lief and confidence. 

The significance of the step is enormous. Although 
not directly involving Government ownership it does 
mean the nationalization of the railway system, and 
many Congressmen have said that the continuance of 
Government control for all time depends entirely upon 
the success attending this experiment. If necessary for 
the welfare of the nation at a moment when inefficiency 
dare not be tolerated, it will be logical to ask why public 
business should be subjected again to demonstrated 
wastefulness and inefficiency in times of peace. If the 
War is to bring any great and lasting benefit it must be 
found in the amelioration of the conditions of human 
life, and the pivotal question around which revolve the 
social struggles that have disturbed the world since the 
growth of the factory system is that of reducing the 



hardships of gaining a proper livelihood. Economy in 
the distribution of commodities is of the utmost im- 
portance in planning to alleviate the burdens that press 
upon the people. In the first months after we entered 
the War it btcame evident that the two largest factors 
in the high cost of living were the evils of profiteering 
and the inefficiency of transportation. The Government 
unhesitatingly grappled with the first of these so as to 
inspire confidence that the middleman will be regulated 
within another year in such manner as to perform a use- 
ful function as a public servant ; and now the solution of 
the transportation problem is undertaken by a master- 
stroke that promises long-needed relief. It is doubtful if 
the owners of railway stocks and bonds will consent to 
have their properties returned after the War to the con- 
trol of financiers and speculators who would manipulate 
them for narrowly selfish purposes as they were accus- 
tomed to do in the past. 

The ownership of nearly one-third of the railroads of 
the world has already been vested in the governments of 
the respective countries where they operate. In the British 
dominions 55% of the mileage is so controlled, and the 
entire 24,000 miles of railroad in Great Britain itself is 
temporarily and successfully administered by a Royal 
Commission. The action of President Wilson affects 
265,218 miles of railroad in the United States, making a 
total of 502,228 out of a world-mileage of 713,120 now 
operated as public utilities. The time has gone when we 
need fear political graft and perfunctory service in the 
administration of nationally controlled enterprises. The 
Post-Office is a shining example of efficiency and 
economy. The Panama Canal has afforded another in- 
structive object lesson, enlarging the confidence in Gov- 
ernment ownership and control that had been created by 
such beneficent projects as that of the Sault Sainte 
Marie locks and canal, which have made possible the 
great expansion of our iron and steel industry. Gov- 
ernment work today is conducted on business principles, 
for civil service reform has spoiled the larger opportuni- 
ties for private graft. Railroad employees will pass 
under similar rules, affording them protection greater 
than any they can secure through the costly mechanism 
of labor organizations. They recognize already the ad- 
vantages flowing from their new status as Government 
employees, in consequence of the announcement that the 
exorbitant salaries of the high officials are to be trimmed 
down, thus enabling higher remuneration to be offered 
to the humbler workers. It is evident that the salaries 
paid to senators, departmental heads, bureau chiefs, and 
other responsible officers of the Government, will con- 
stitute a measure of the stipend appropriate for the man- 
agers of the railroad system. It is perfectly under- 
stood that the princely rewards distributed among rail- 
way officials have been in recognition of special ability in 
aggressive competition, in financial manipulation, and in 
the control of politics and legislation, rather than for 
services in the routine of practical operation. Under Gov- 
ernment control the need for such qualifications instantly 



January 5, 1918 



MINING and Scientific PRESS 



disappears, and incidently one cause of political corrup- 
tion thereby will be eliminated. The great organizations 
maintained for the solicitation of patronage will now be 
unnecessary, and many of the minor competing lines can 
be consolidated, not only insuring better service, but re- 
lieving them from an unnecessary burden of adminis- 
trative expense. The wastefulness of separate terminals 
will be greatly reduced ; the luxurious and half-filled pas- 
senger trains will be adjusted to the actual needs of the 
traveling public; the tourist business, especially during 
the continuance of the "War, will no longer embarrass 
more necessary service. Under the old system many of 
these extravagances were unavoidable. To a large ex- 
tent the duplication of roads and terminals, and the con- 
sequent overhead cost, were the only means that offered 
escape from crushing monopoly. The profligacy of the 
system stands out in strong relief as soon as we contem- 
plate a single national system operated for the welfare 
of the whole people. Major Smith "W. Brookhart, one 
of the best-known railway statisticians in the country, 
recently estimated that Government ownership would 
save $400,000,000 per year through elimination of com- 
petitive waste, and $500,000,000 in interest upon funds 
required for betterment because of superior Government 
credit. Major Brookhart 's figure for the saving to be 
made by abolishing competition is regarded as conserva- 
tive. No less capable a witness than C. P. Huntington 
affirmed some years ago that the competitive waste in 
New York City alone amounted to $100,000,000 an- 
nually. It is likely that the consolidation now consum- 
mated will effect economies in excess of a billion dollars 
per year, quite apart from the advantages of effective 
assembly of military supplies and the cheaper and more 
systematic distribution of the necessaries of life through- 
out the United States. On the outbreak of hostilities in 
Europe the railroad managers, professing not to realize 
the inevitable expansion of business that would ensue, 
took a pessimistic view of the industrial future of the 
United States. At a moment when orders for equipment, 
barely adequate for the needs of normal traffic, might 
have been placed at most advantageous prices, they cur- 
tailed the outlay for maintenance and improvement. A 
few months later, when the flood of war-orders from 
England and France began to inundate our manufac- 
tories the railroads proved unequal to the task of han- 
dling the business successfully, and operating costs were 
increased by the necessity for ordering rolling-stock and 
other supplies at war-prices. Under Government control 
it would be possible to take advantage of periods of 
market depression to provide needed equipment, and 
this would act as a stabilizer of industrial conditions. 
Already the Administration has suggested the necessity 
for providing money to make good the shortage of roll- 
ing-stock. All the funds that are needed can be secured 
on guaranteed bonds at 4%, where privately owned roads 
would have to pay from 5 to 6%. Moreover, it is under- 
stood that the Government will seek authority to pur- 
chase such new securities, thereby becoming a creditor 



anil looking toward permanent control of our national 
transportation system. The real owners of the railroads 
long have been the general public. They now find them 
selves protected as never before, through the Government 
guarantee of dividends based upon the average return 
for the last three years. The effect on the minds of the 
people has been registered by the sudden rise of quota- 
tions on railway stocks. No step that President "Wilson 
has taken has met with more popular approval than the 
nationalization of the American railroads. It makes for 
unity of effort in winning the War, for higher efficiency 
in our whole industrial system, and for reduction in the 
cost of everything that enters into the life of the people. 

Gold and Credit 



Although the threat to discriminate against freightage 
for gold mines has been withdrawn, it will be well for 
every thoughtful citizen to be on his guard against an 
economic heresy that would do much worse than threaten 
the welfare of a part of our mining industry — it would 
endanger our solvency as a nation. The net gain of 
gold to the United States from August 1, 1914 — the day 
the "War began — to November 16, 1917, is stated officially 
to be $1,082,212,000. This gain is impressive, but it is 
small compared with the indebtedness being incurred at 
a growing rate by the Government for the purposes of 
the "War. The expenditure in one year is twenty times 
as much as the value of the gold accumulated in three 
years. It is no wonder that the use of gold coins for 
Christmas presents was discouraged by those in au- 
thority nor that an embargo has been placed upon the 
export of this basic commodity. "We must keep our gold 
where it can perform the greater service, and we should 
intensify the mining of the ore that will yield more of it. 
"We shall need it, if we are to emerge financially safe out 
of the morass of international credits. The expansion 
of bank-credits caused by the flotation of huge govern- 
ment loans in Europe and in this country since the "War 
began is tending to produce world-wide inflation, such 
inflation as is inevitable when a government borrows 
faster than its people are able to save. As Mr. Adolf C. 
Miller, of the Federal Reserve Board, has indicated, the 
rise in prices of all commodities is due to the fact that 
the purchasing media — bonds, notes, and other forms of 
credit — are being produced faster than the commodities 
themselves. ""When the supply of currency and credit 
in its increase outruns the supply of purchasable goods, 
the price of goods must rise," says Mr. Miller. That is 
sound doctrine. Let us see now where it leads us. The 
normal, conservative, credit-expanding power of gold is 
usually taken at about the ratio of seven to one, that is, 
the gold reserve of the United States, now estimated at 
$3,089,000,000, is good for a volume of adequately se- 
cured commercial paper amounting to a little more than 
21 billions of dollars. Moreover, the expansive power 
of the British gold reserve is also being utilized in this 
country through the fiscal agents of Great Britain, thus-

adding to the volume of credits available, while exchange 
is protected through daily purchases of surplus bills 
drawn against London, thus stabilizing the value of the 
pound sterling. In effect, the British banking system 
has become unified with that of the United States, and 
other allied countries are doing the same. Accordingly 
no paralysis of credit is in sight at present, and our re- 
sources have not yet been over-strained. The available 
inter-allied credit-limit is not far short of 40 billions of 
dollars. On the other hand, the increase in the nominal 
value of commodities represents a shrinkage of purchas- 
ing power, so that the commodity-volume to which the 
expanded credits apply has actually cut our financial 
resources nearly in half, viewed with relation to sup- 
plying the needs of our own country and of our Allies. 
This explains what Mr. Miller meant when he pointed 
out the disproportionate increase of credit-paper over 
the corresponding actual volume of commodity-output. 
The ultimate effect would be disastrous were prices to 
fall at the end of the War. That would mean ruinous 
liquidation. Apparently the stability of business de- 
pends in no small degree upon maintaining the scale of 
prices and wages established under the stimulus of the 
wild speculation that followed the receipt of big war- 
orders from Europe in 1915 and 1916. Had our political 
leaders foreseen, as did a few of our broad-minded 
financiers and political economists, that this was our 
war from the moment when the Germans, frustrated at 
the Marne, began to dig themselves in for a long and 
stubborn contest, we would not have disturbed the 
financial structure of America and the world by pro- 
ceeding to exploit the nations then involved in the strug- 
gle against Prussian aggression. The mob of commis- 
sion men had much to do with adding to the enormous 
cost of supplies in the earlier period of the War, but, 
after this evil had been corrected in part, the manu- 
facturers continued to quote prices out of reason, as the 
soaring quotations of industrial stocks accurately re- 
corded at the time. It is not to be expected that the 
laboring man and the producer of raw materials will 
consent to receive the pay corresponding to periods of 
normal business when the evidence of profits that can 
multiply the value of stocks many times over is pre- 
sented daily to him in the stock-exchange reports. Failure 
to realize our grave responsibility at the right moment, 
coupled with our persistence in squeezing the last dollar 
we could get from the nations that were then fighting 
the battles that protected us from the Prussian menace, 
has precipitated a new difficulty that calls for the wisest 
statesmanship and the soundest finance. Inflation of 
prices has resulted, and the world must not only adopt 
these fictitious values, but may need to maintain them 
for an indefinite period, in order to avert collapse. Our 
dollar is no longer the dollar o'f 1914; it is about 58 
cents as compared with the purchasing power of the 
dollar of that period. The dollar of today is an altered 
monetary measure, and it will require more gold to 
■cover the transactions of the future in equal quantities 
of wheat and corn and meat than it did in the past. To 



talk of restricting the accumulation of a gold reserve at 
a time when the purchasing power of the dollar has 
shrunk one-half is to limit the volume of credit to a 
point that will prove insufficient for the growth of com- 
merce. Fortunately Great Britain and the United 
States have a corrective in their resources of gold-bear- 
ing ore. Between them they control directly 80% of 
the world's annual production of that metal, and indi- 
rectly at least 10% more. The gold production of the 
world is $450,000,000 — not much in these days of billion- 
dollar loans, but enough to stiffen the base on which a 
vast system of credit is reared. Of the world's silver 
the British dominions produce 30,000,000 ounces and 
the United States 75,000,000 ounces, out of a world's 
total of 177,000,000. Indirectly the Allies control the 
output of at least 50,000,000 ounces more, so that 155,- 
000,000 ounces, worth now about that many dollars, is 
available annually for maintaining the basis of credit. 
Thus the two English-speaking Allies, by their own 
mineral resources and the enterprise of their citizens in 
other regions, control 90% of the precious-metal produc- 
tion forming the hard bottom of international credit. 
The enemy countries — Germany and her vassals — can- 
not place their hands upon more than 2% of the gold 
and silver annually produced. This is a factor of prime 
importance at this juncture in the world's history. It 
represents a decisive economic advantage, if properly 
utilized. In conjunction with the reserves on hand, it 
constitutes an adequate foundation for a complete and 
well-balanced industrial organization, outside the con- 
fines of any Teutonic hegemony. We can suffer the 
Hun to rage within the barbed-wire entanglements that 
now fence about his empire of wrath. The nations out- 
side possess nearly five-sixths of the total gold and silver 
that is so necessary for universal credit and exchange. 
This is exclusive of the reserves that the old regime left 
in the State Bank of Russia. Despite the improvident 
exaggeration of prices that was induced largely by a 
scramble for sudden wealth through war-contracts, and 
which, like a noxious germ, has developed its own 
toxin in the form of an attenuated dollar, the exterior 
nations are prepared, both industrially and financially, 
for continued growth as a world apart. Even the ab- 
straction of materials for belligerent uses may not defeat 
the natural expansion of industry when it is considered 
that all elements are available, and in a quantity greater 
than served the needs of commerce before Germany and 
her ames damnees became barred from intercourse with 
the champions of freedom. Problems of extremest 
gravity, no doubt we have; conservative financiering 
must guide us in meeting the changed conditions brought 
on by top-heavy governmental burdens ; but the spectacle 
of a world provided with all the essentials, so that the 
maintenance of commercial equilibrium does not require 
the Central Powers, is a pleasing thought as we step 
into the New Tear. It suggests an adjustment between 
the free nations of the world that will ease the economic 
hardships that have been so pronounced at the begin- 
ning of the struggle.

Water in Stamp-Milling 

The Editor: 

Sir — There are many and varying factors that govern 
the ratio of water to ore in stamp-milling. Recently 
there came to my attention an example of present prac- 
tice ou the Mother Lode, California. 

Crushing with 950-lb. stamps, through a 20-mesh 
screen, at 110 drops per minute, a 7i-in. drop, and a 
low discharge, the output per stamp is 7.5 tons per 24 
hours. The ratio of water to ore is 2.4:1. The pulp 
flows over amalgamating plates having a fall of one 
inch to the foot, thence to tables. 

One would expect with an output of 7.5 tons per 
stamp per 24 hours a water-ratio approximating 5 or 6 
per ton of ore. Seeing a high crushing-duty was de- 
sired, the question naturally arises why so little water 
is employed, water being plentiful. It appears beyond 
controversy that, within limits, an increased water- 
supply gives an increased output, by liberating the par- 
ticles when ground. Would an increase of water in this 
instance have added to the already high stamp-duty? 

In modern milling practice, using coarse crushing, a 
water-ratio of at least 6 : 1 appears necessary to wash 
rapidly the coarser particles through the screen. I in- 
fer, therefore, since water is the vehicle of discharge, 
that coarse crushing requires a higher water-ratio than 
fine crushing. The point I wish to bring out is this: is 
not the tonnage crushed high relative to the water used, 
and would the output not be further increased by an 
addition of water? 

Possibly other workers on the Mother Lode may afford 
further data.

Scotch Philosophy and the Lead' Smelters 

The Editor: 

Sir — The greatest glory of Scotland, one of the high- 
est honors that could be possessed by any nation, is 
found in the achievements of those transcendent intel- 
lects which adorned and embellished her literature in 
the latter part of the 18th century. During that period 
there sprang forth from her bleak and misty hills upon 
an astonished world the amazing and comprehensive con- 
ceptions of Adam Smith, the clear and skeptical logic of 
Hume, the profound and far-reaching discoveries of 
Black. Adam Smith produced order from the chaos of 
the collective actions of men. His '"Wealth of Nations' 



and the ideas contained in that monumental work trans- 
formed the English policy of trade. Hume, with un- 
parallelled lucidity, tore the mask from superstition and 
cant, and lastly Black made his generalizations on the 
existence and behavior of latent heat. Lesser lights in 
the constellation of Scottish greatness might be cited, 
but the object here is not to exalt Scotland, but to 
justify a system of thought that appears to have been 
transplanted to America, and to have further justified 
itself by success in American industrial fields, as well as 
in the Scotch philosophical world. 

It is not my purpose to tire the reader with prolix 
philosophical distinctions between the various methods 
of reasoning. There are, however, two sharply defined 
systems of thought, one being known as the 'inductive' 
method, and the other as the ' deductive. ' The inductive 
was, and probably is, the typical English method. In 
this system great stress was laid upon experimentation, 
and the proving of principles by a multitude of facts. 
The deductive method, on the other hand, by great flights 
of the imagination, established its principles and pro- 
ceeded by 'deduction' to arrive at results without the 
laborious efforts required by the opposite system. 

Perhaps no field of American industry displays a more 
profound knowledge, or greater skill in the application 
of the principles that underlaid the work of the Scotch 
philosophers, than the one occupied by the lead-smelters 
A thorough study of the typical settlement sheet dis- 
plays an intricate — indeed, a dazzling and incompre- 
hensible^ — knowledge of deductive methods. The men 
who outlined the process of ore-buying, of which a set- 
tlement sheet represents merely a summary, show a rare 
skill, which for general scope compares favorably with 
Adam Smith, and for finish and touch, was never ex- 
celled by the delicate efforts of Hume. An instance to 
the point is where the smelters make a deduction of 1% 
for moisture regardless of any efforts to prove inductively 
that it is there. In fact, the magnificent sweep of their 
intellects steps over the presence of such a small item. 
It is sufficient for these able men that they make a fitting 
and proper application of their basic principles. 

Their next step is to ascertain what percentage of lead 
is contained in the ore. This they first firmly establish, 
ignoring the old fire-assay, which, of course, is low. By 
latter-day methods the amount of lead in the ore is de- 
termined. Once this point has been reacked, deduction 
philosophically steps in and proves incontrovertibly that 
although the lead is not absent, neither is it all present, 
and no matter what is there, there are two units less 



8 



MINING and Scientific PRESS 



January 5, 1918 



than whatever it may be. Thus is the antiquated fire- 
assay reconciled to its more modern successor by a clever 
adjustment of differences that, in the end, leaves every- 
thing pretty much as it was in the beginning, and ob- 
viates any confusion that might have resulted from the 
introduction of the later method. 

The reader's attention should now be concentrated 
with particular intensity upon the next step. Here, un- 
less great care be taken, one will be apt to jump to the 
conclusion that deductive methods are being ignored, as 
with apparent abandon they yield the seller 90% that 
may exist at this stage of the deductions. Reflection, 
however, will show that the smelter is entirely consistent 
and that a little thought on the part of the reader, with- 
out further argument, will prove that precisely the same 
result may be reached by deductively abstracting 10% 
from the amount existing at the stage marked by the 
beginning of this paragraph. 

"We now come to the master-stroke, the point where 
the deductive process becomes overwhelming to the 
mere miner. There is another fine touch here, a neat 
and clever distinction, and at bottom a profound appre- 
ciation of the difference between scientific and empirical 
knowledge. If lead is selling at five cents per pound, 
and the smelter usually determines whether it is or not, 
one and one-quarter cents is deducted presumably for 
shipping, refining, and selling expense. After the price 
has passed the five-cent mark, one-quarter of a cent is 
deducted for each cent paid over five cents. Now, with- 
out reflection, the average person will no doubt con- 
sider that the deduction before the five-cent price, and 
the deduction after the five-cent price were one and the 
same thing, and that after all a 25% deduction would 
attain the same result as the more complicated system. 
It is manifest, however, without recourse to any fine 
reasoning, that the cost of refining, shipping, and sell- 
ing does not vary with the market-price of the lead, and 
that the smelters must be guaranteed a reasonable com- 
pensation for this service independent of the price of the 
product. Here for once we find a deduction that is not 
the result of deductive reasoning. It should be noted, 
nevertheless, that the deduction, although not deductive, 
cannot be said to be inductive, as the facts upon which 
this deduction has been based have not been established 
as actually existing. In other words, the smelter has not 
proved that the costs are actually one and one-quarter 
cents, but might be any figure, say one-half a cent, one 
cent, or even two and one-half cents. After the price 
has passed five cents, however, the smelters come again 
under the unrestricted sway of their deductive princi- 
ples. One-quarter of a cent per pound here means 25% 
Df the value of the lead, a splendid stroke as the most 
enthusiastic inductive philosopher would he obliged to 
admit. 

For years the Americans have been branded as mere 
money-makers, dollar-chasers, and Mammon-worshippers. 
We were held up to view as a people glorying in vain 
shows of power and wealth, sensual ambitions, and all 
forms of material success. The refinements and intel- 



lectuality of Europe were supposed to be wanting in our 
lives. We were a nation devoid of ideals, uncultured, un- 
couth, and altogether beneath the more refined civiliza- 
tion of the older nations. But is this found to be true? 
Have we not, ^>n the contrary, discovered that some of 
our biggest business men are steeped in the learning and 
wisdom of by-gone days? Is not every action found to 
be guided by deep-set principles? Acts, heretofore in- 
scrutable, have become understandable. What previous- 
ly has appeared capricious is suddenly shown to be gov- 
erned by reason and logic ; and as a great scientist will, 
from a multitude of apparently unrelated and chaotic 
facts, formulate a theory that will disclose an almost 
divine order and system, in the place of a supposed dis- 
order and confusion, so do we see here, through an under- 
standing of the great Scotch philosophers, that the ap- 
parently capricious and arbitrary deductions of the 
smelters are only what a philosophical mind should 
reasonably expect.

Geology of the Success Mine 

The Editor: 

Sir — There has been considerable controversy as to 
priority of the ore and monzonite (locally known as 
granite and will be so designated hereafter) in the 
Success mine, in the Coeur d'Alene. F. L. Ransome of 
the U. S. Geological Survey, in Professional Paper 62, 
took the view that the granite was there first. Oscar H. 
Hershey, after an extensive examination, concluded that 
the granite was post-mineral, and so expressed himself in 
a paper in the Mining and Scientific Press about two 
years ago. Joseph B. Umpleby followed this with an ex- 
amination about a year ago and confirmed Mr. Ransome. 
Mr. Umpleby based his conclusions upon the replacement 
of the granite by ore, which he determined by sections 
under the microscope. Not being a geologist I am un- 
familiar with the proper weight to be attached to micro- 
scopic work, but, from a physical point of view, there 
always appeared to me to be a doubt, since, in all speci- 
mens of granite containing stringers of ore, these are in- 
variably a continuation of quartzite stringers partly re- 
placed, and the question always comes to my mind 
whether these stringers might not be a replacement of 
quartzite stringers in the granite, the quartzite having 
been entirely replaced. I have, however, recently ob- 
tained a specimen of a nodule of granite entirely sur- 
rounded by ore. A chunk of apparently solid ore was 
broken open and found to contain a nodule of granite 
nearly as large as a hen's egg. It was taken from a spot 
where numerous stringers of granite extended into the 
ore. The neck of granite which connected this nodule to 
the parent body must have been wholly replaced by ore. 
This seems to me to give conclusive proof that the granite 
was there first. If I am mistaken I am willing to be cor- 
rected.

The Story of the U. V. X, Bonanza— I 



By' T. A. RICKARD 



The most remarkable discovery of ore made in recent 
years is that which has given more than local fame to 
the United Verde Extension mine, at Jerome, Arizona. 
Jerome 1 is in Yavapai county and 25 miles north-east of 
Prescott, formerly the capital of Arizona and always an 
important, mining centre. See map, Fig. 1. For about 
forty years Jerome has been identified with the United 
Verde mine, although the first claim 2 in the district was 
located as early as 1876. The ground now included in 
the United Verde is said to have been worked for silver 
ore between 1880 and 1885. No silver-reduction plant, 
however, was erected. The ore was smelted for copper 
as early as 1883, when a 42-inch water-jacket furnace 
wes erected. The president of the company that operated 
the United Verde at that time was F. A. Tritle, formerly 
governor of Arizona, and still earlier the manager of the 
Yellow Jacket mine on the Comstock lode. The secretary 
and treasurer of the company was Eugene Jerome, of 
New York, and it was after him that the town of Jerome 
was named. This company produced a considerable 
quantity of copper, in the form of black copper and 

'On a map accompanying a paper by the late John P. Blandy 
on 'The Mining Region Around Prescott, Arizona,' in Vol. XI, 
Trans. A. I. M. E., the position oj Jerome is indicated by the 
name 'Wade Hampton' and the description 'Copper mines.' 
This paper was read in February 1SS3. 

2The Verde, so named on account of the green stains of cop- 
per, is usually mentioned as the first claim located in the dis- 
trict, but, on inquiry, I find that the Verde was located on 
May 16, 18S6, whereas the Azure (another reference to oxidized 
copper mineral) Northwestern, Azure Southeastern, Chrome 
Northwestern, Chrome Southeastern, Eureka, and Wade Hamp- 
ton claims constituted the earliest group of locations. Of 
these the first to be recorded was the Chrome Southeastern, 
on February 19, 1S76, by John O. Dougherty and John P. 
Kelly. 



matte, until 1887, at which time the resources of the mine 
appeared to be depleted. In 1888 William A. Clark, 
subsequently Senator from Montana, bought the prop- 
erty and started fresh exploratory work. 

In 1884 Mr. Clark was appointed commissioner to rep- 
resent the State of Montana at the New Orleans exposi- 
tion. Among the mineral exhibits he noticed some sam- 
ples of copper ore from the United Verde mine ; these in- 
terested him because the assays attached to the speci- 
mens showed that gold and silver were associated with 
the copper. In his usual methodical manner he recorded 
a note on the subject. Returning to Montana, he forgot 
about it. His mines at Butte, which were highly produc- 
tive, supplied ore to the Port Orford Copper Co. in New 
Jersey. When this refinery went into liquidation, in 
1886, Mr. Clark was one of the chief creditors. He 
assumed the control of the refinery and operated it for 
a year or more. When examining the records he found 
assays of shipments of ore from the mine in Arizona 
that had supplied the specimens he had noticed at New 
Orleans. Thereupon he sent Joseph L. Giroux to ex- 
amine the United Verde. Mr. Giroux found that the con- 
trolling interest in the property was under option to 
some people represented by James Douglas, so he ar- 
ranged to have the refusal. Dr. Douglas decided not to 
exercise his option, because, so I am informed, the lode 
was spotty; whereupon Mr. Giroux informed Mr. Clark, 
who came at once, and, after an inspection, purchased 
70% of the stock, acquiring most of the remainder in 
after years. The Senator for Montana had no liking for 
geologists, he did not retain a geologist on his staff, and 
he excluded visiting geologists. Therefore he failed to 
inform himself concerning the geologic structure of the 
Jerome district, and it remained for the son of Dr.

Douglas, as we shall see, to find and develop a mine as 
rich as the United Verde in the immediately adjacent 
ground. 

In 1892 the United Verde paid its first dividend and 
shortly thereafter this mine took rank as one of the great 
copper enterprises of the world. The United Verde has 



not permit visitors to inspect his mine, his policy being 
to exclude operators from the vicinity. 

In 1900 a surveyor named J. J. Fisher located a frac- 
tional claim out of which grew the enterprise now known 
as the United yerde Extension. Fisher was not in the 
employ of Clark; he was a U. S. Deputy Mineral Sur-

produced 800,000,000 pounds of copper and is credited 
with a reserve of ore likely to yield as much more. 

During the greater part of its history the Jerome dis- 
trict was a 'one-mine' camp. It could boast only one 
noteworthy enterprise. No extension of the United 
Verde orehodies was found, mainly because a master- 
fault with a big throw spoiled the chance not only of 
tracing the ore-zone but of exploring the adjacent 
claims, except at a prohibitive cost. Senator Clark did 



veyor and in that capacity had been employed occasion- 
ally by Clark and by others in the district. At the time 
when he discovered this fraction of vacant ground he 
was surveying for the late George "W. Hull, a successful 
miner, merchant, and State legislator, who had lived at 
Jerome for many years and was keenly alive to the im- 
portance of tracing the United Verde ore-zone into out- 
side ground. Fisher found a fraction covering less than 
an acre, between the March claim, belonging to Hull,

name of the Little Daisy and piTsuaded L. E. Whicher 
to take an option on the property, the latter selling 
enough stock to start the sinking of a shaft, under the 
guperintendency of E. A. Powers. That was in 1900. 
This shaft was sunk 300 ft. through the lava and lime-

At about 100 ft. the shaft penetrated ground that 



In order, however, to explain the true relation of 
Fisher 'b enterprise to that of Hull, it is necessary to 
record the vicissitudes of early exploration and promo- 
tion. In 1899 the first company to prospect this area 
was organized by Hull ; it was called the United Verde 
Extension Gold, Silver & Copper Mining Co.; it became 
known as the U. V. X. and its successors have had the

showed signs of ore, but nothing of value was discovered 
in the drifts and in 1901 operations ceased. The enter- 
prise seemed to be blighted by the fact that the most 
promising workings were within a hundred feet of the 
March claim, owned by Hull, as already stated. Fisher 
found it difficult to obtain any additional financial aid 
and the Little Daisy remained idle until Mr. "Whicher 
acquired the claim for 5000 shares of a company that 
he organized in 1906, and shortly thereafter the shaft 
was deepened to 800 ft., again under Fisher's direction. 
He unfortunately did not live to see his hopes fulfilled, 
for he died in 1911. 



Throughout Arizona the mine is known by its initials. 
This first company controlled a dozen claims, including 
the territory directly west of the United Verde, with the ' 
ground north and south, so as to enclose Senator Clark's 
property on three sides. This company was capitalized 
for 300,000 shares of $10 each, and was organized under 
the laws of Arizona. In March 1899 Louis E. Whicher, of 
Schofield, Whicher & Co., at Boston, became interested in 
the promotion of the company at the instance of the late 
Franklin Farrell and associates. At the last moment 
Farrell had some disagreement with his associates and 
withdrew, but Whicher proceeded with the business, the

result being that he and his clients acquired 190,000 
shares, Hull retaining 110,000 shares. Mr. Whicher be- 
came the largest individual shareholder, his holdings rep- 
resenting $100,000, which also was the amount of cash 
available for exploratory work. A shaft was sunk on the 
claim called '1888' (See map, Fig. 2), this shaft being 
within a stone's throw of the United Verde shaft. Mr. 
Whicher obtained the professional advice of a competent 
engineer, Milton F. Johnson, and was encouraged in the 
belief that if there were any ore to be found outside the 
United Verde, it would be east of that property. At this 
time, in 1900, Fisher had located the Little Daisy frac- 
tion, and was trying to get money for prospecting. 
Whicher obtained an option on the Little Daisy for 
$50,000 and sank a shaft upon it to 300 ft., of which 125 
ft. passed through oxidized coppery rock, too low-grade 
to be ore, but so promising that Mr. Whicher was 
prompted thereby to begin negotiations with Hull for the 
acquisition of the claims adjoining the Little Daisy, 
namely the March, Conglomerate, Iron Carbonate, and 
Bitter Creek locations. This transaction followed upon a 
curious episode. In 1900 Hull had begun divorce pro- 
ceedings at Providence, and was arrested on the train, 
while passing through this town, for having sworn in- 
correctly that he was a resident of the State of Rhode 
Island. At this juncture he appealed to Whicher to help 
him out of his predicament ; Whicher took Hull to Boyd 
B. Jones, of Boston, then District Attorney of Massa- 
chusetts, and by his aid Hull was extricated from his 
entanglement. The immediate sequel was that Hull, now 
in a docile state of mind, made a trade with Whicher, 
whereby Hull transferred his 110,000 shares to the U. V. 
X. company and also deeded the four claims above-men- 
tioned, in exchange for the properties originally owned 
by the U. V. X. company. These four claims had been 
incorporated under the name of the King Development 
Co. In return, the U. V. X. company transferred to Hull 
all the various claims that it owned around the United 
Verde property. By this exchange the U. V. X. com- 
pany became the owner of Hull's four claims and, shortly 
thereafter, of the Little Daisy fraction, which Whicher 
acquired for the company from Fisher for 5000 shares 
of U. V. X. stock. 

These deals having been consummated, the U. V. X. 
company was re-organized, in 1902, under the laws of 
Maine, but with the same capitalization, namely, 300,000 
shares of $10 each. In 1910 another re-organization was 
effected, this time under the laws of Delaware, the capi- 
tal being increased to 400,000 shares of the same par 
value. 

Meanwhile Mr. Whicher persisted in his prospecting. 
The Little Daisy shaft was sunk to 800 ft., and a search 
for ore was made under Fisher's direction. From 1907 
to 1911 C. C. Burger was consulting engineer to the com- 
pany and showed sustained confidence in the outcome of 
the exploratory work. In March 1911, Mr. Whicher 
arranged for an examination by B. M. Atwater, Jr., 
who reported favorably. In his report, which is before 
me as I write, Mr. Atwater stated that his experience led 



him "to expect high-grade copper orebodies at or near 
the water-level." He concluded by stating: "I believe 
the chances of finding valuable orebodies are excellent." 
This is dated April 8, 1911. At the same time Mr. 
Burger reported the finding of ore assaying 2.6 to 
3.1% copper, with $2 in precious metals, in a winze then 
65 ft. below the 800-ft. level. The copper was in sulphide 
form, but it showed signs of leaching. This 'near-ore' 
looked promising, but a more important find was a patch 
of 39 to 42% ore cut in an eastern cross-cut from the 
700-ft. level. This chalcocite ore was 5 ft. wide and 15 
ft. long, averaging 18.7% copper, as stated by Mr. 
Burger. Along the 800-ft. level a much larger body of 
low-grade oxidized material had been exposed and its 
downward persistence was indicated by the winze. Yet 
the enterprise languished. The finding of the chalcocite 
patch caused the shares to jump to $4. It was a mere 
flash in the pan. Several other experts came to Jerome 
to make an examination, they reported adversely, and 
in kindness to them I abstain from giving their names. 
They accounted for the copper in the schist, particularly 
in the main east cross-cut from the 800-ft. station, by 
supposing it to be due to solutions originating in the 
United Verde orebody. The patch of chalcocite failed to 
impress them. In the summer of 1911 Whicher inter- 
ested Theodore Gross and A. Chester Beatty in the ven- 
ture and on Mr. Beatty 's initiative a mining geologist of 
acknowledged ability inspected the U. V. X., but he re- 
ported that the conditions were unfavorable. 

Up to this time about $500,000 had been spent in the 
search for a real orebody. Fisher had been serving as 
manager for the U. V. X. company until January 1911, 
when he was succeeded by Thomas A. Varden, of Butte. 
Mr. Whicher was president of the company. 

In 1908 Major A. J. Pickrell had purchased stock 
from Fisher and for a time he had served as a director 
of the company. Through him the U. V. X. was des- 
tined to obtain the financial assistance needed to bring 
the enterprise to fruition. In December 1911, shortly 
before Fisher died, Major Pickrell wrote to James S. 
Douglas, urging him to come to Jerome and look into 
the business. Mr. Douglas is the son of James Douglas, 
the dean of copper mining in Arizona, long identified 
with Phelps, Dodge & Co., and with all that is honorable 
and scientific in the mining industry of the South-West. 
In April 1893, while James S. Douglas was in charge 
of the Senator mine, ten miles south of Prescott, he came 
to Jerome to repair a compressor-shaft, simply because 
Senator Clark's machine-shop at the United Verde mine 
was the nearest available. Subsequently he visited Jerome 
a number of times to see George Hull, and in this way he 
acquired some familiarity with local conditions. In June 
1899 he met Colonel D. P. Bosworth, of Marietta, Ohio. 
the enthusiastic promoter of the Verde Queen mine, which 
is on the limestone cap just east of the town of Jerome. 
The Colonel had uncovered a little carbonate ore in the 
bed of Bitter creek on the Columbia and Verde claims, the 
latter an early location covering the ground on which 
Mr. Douglas's house now stands. Bitter creek crosses

the line of the big fault and collects the drainage of the 
hillside below the United Verde mine. This property of 
Colonel Bosworth was re-organized later, becoming the 
Jerome Verde, now prominent among the prospecting 

ventures in the district. Bosworth consulted Douglas, 
who. in this way, obtained some further knowledge con- 
cerning the loeal geology. Upon his arrival at Jerome 
in December 1911, on the invitation of Pickrell, as al- 
ready stated, Douglas was shown the workings on the 
800-ft. level of the D. V. X., but he was unable to ex- 
amine the winze or the lower workings, then down to 



business. whereupon .Major Pickrell again urged the 
younger Douglas to interest himself in the enterprise — 
tli is time suceessfully. 

In the summer of 1912 Mr. Douglas and George E. 
Tener, of Pittsburgh, took the venture in hand and in- 
vited their friends to join them in providing $225,000 
for the development of the property. These two gentle- 
men decided that it was futile to attempt further search 
for ore from the bottom of the Fisher winze, but that the 
prospect justified the sinking of a new shaft at a spot 
2000 ft. east of the Little Daisy shaft. Under date of

1200 ft., on account of water. However, what he saw 
impressed him so favorably that negotiations were com- 
menced, leading to an option. This option was submit- 
ted to Phelps, Dodge & Co., whose counsel ("William 
Church Osborn) at New York, disapproved of the trans- 
action on account of some fancied defect in the title, 
in which supposition he proved to be wrong. The or- 
ganization of the U. V. X. company and the examination 
of titles had been placed by Mr. Whicher in the hands 
of Brandeis, Dunbar & Nutter, the senior member of this 
firm being Louis D. Brandeis, now a Justice of the U. S. 
Supreme Court. Dr. James Douglas and his associates 
were favorably disposed to the deal, but the technical 
objection of their legal adviser caused them to drop the 



August 14, 1912, they sent the following letter to a num- 
ber of mining engineers, metallurgists, and mine op- 
erators : 

"George E. Tener and J. S. Douglas have secured an 
option on 450,000 shares of stock of the United Verde 
Extension Mining Company. 

"The United Verde Extension Mining Co. is capi- 
talized at $750,000, 3 with 1,500,000 shares of a par value 
of 50 cents each. 

"The original stockholders own, in round numbers,

cents each, as compared with the former capitalization of 
500,000 shares of $10 each, as covered by the contract between 
Douglas and Whicher, the president of the company.

400,000 shares, and George B. Tener and J. S. Douglas 
have an option on 400,000 shares and have paid $25,000 
into the treasury of the company for 50,000 shares. 

' ' 500,000 shares will be left in the treasury. 

"The option on the 400,000 shares runs to June 15, 
1915, and the shares are to be purchased as the Treasurer 
may require funds for development work, at the discre- 
tion of the Board of Directors who will be controlled by 
Mr. Tener and Mr. Douglas. 

"As a commission for services the United Verde Ex- 
tension Mining Company are to pay Mr. Tener and Mr. 
Douglas 150,000 shares proportionately as the money is 
placed in the treasury. A proportion of the stock re- 
ceived by Mr. Tener and Mr. Douglas as commission 
from the United Verde Extension Mining Company is 
being used by them for organization purposes, but to 
comply with the law of the State of Delaware it must be 
issued to them for services rendered. 

"They propose to extend to you the privilege of sub- 
scribing for .... shares at $0.50 per share, equals $...., 
this subscription being subject to the call of the Treas- 
urer, Mr. C. P. Sands, at 280 Broadway, New York, 
who will most likely call for 20% of this amount on 
close of this subscription list, and the balance as needed, 
which will probably be at the rate of 20% every three 
or four months. The Treasurer will forward stock to 
you as amounts are received in response to each call. 

"It is proposed to expend $25,000 in development 
work on the present 800-ft. level of the United Verde 
Extension Mining Company's property at Jerome, and 
if the results are satisfactory to expend $200,000 at the 
rate of about $10,000 a month, cross-cutting and drifting 
at that level. 

"Mr. Tener and Mr. Douglas are not asking their 
friends for subscriptions, but believe that their plan for 
the development of the United Verde Extension Mining 
Company's property will result in the discovery of valu- 
able orebodies, and in sending you this letter, it has 
occurred to them that you might consider it a favor to 
be permitted to join in a speculation which they recom- 
mend as such." 

I have given this letter verbatim, so that the reader 
can decide for himself whether it would have caused him 
to take a share in the gamble, for it was that frankly. 
The last paragraph makes it clear that the two pro- 
moters of the enterprise were not begging for financial 
assistance. The letter is unlike the ordinary prospectus 
in that it states the principal conditions plainly and 
truthfully, without any iridescent touches. It seems to 
me that my own response — supposing that I were not an 
editor under a self-imposed obligation not to speculate 
in mines, in order to conserve my position as an unbiased 
commentator — would have been guided entirely by my 
confidence in the integrity of the'two promoters and my 
opinion of their sagacity in such a business. Mr. Tener 
was known to most of the invited subscribers as an ex- 
perienced and honorable mine-operator; he was the or- 
ganizer and one of the directors of the Calumet & Ari- 
zona venture, and he had been connected for many years 



with the Oliver Mining Co., a big iron enterprise in 
Minnesota. He lives at Pittsburgh and is the brother of 
a former Governor of Pennsylvania, John K. Tener. 
But it is no reflection on him to say that it was mainly 
on the recognition of Mr. Douglas's good sense and prac- 
tical experience, plus unquestioned confidence in his 
good faith, that the money was subscribed promptly. 

More than a third of the stock of the company, then re- 
organized as the United Verde Extension Copper Co., is 
held in Arizona. James Hoatson, of the Calumet & 
Arizona Copper Co., visited the prospect and approved 
the venture cordially. He owns 16,000 shares. George 
Kingdon, a Cornish mine-captain,' 1 then in charge at 
Cananea, endorsed it heartily before the new work was 
commenced. Today he owns 18,000 shares. Among the 
other subscribers were Charles Briggs, W. H. Brophy, 
H. Kenyon Burch, Chester A. Congdon, James Douglas, 
Walter Douglas, John C. Greenway, Thomas Hoatson, 
Arthur C. James, L. D, Rieketts, John D. Ryan, Casper 
Schultz, W. D. Thornton, and J. S. Williams, Jr. It will 
be noted that Mr. Douglas's father and brother both 
supported him by taking stock. The money was raised 
by means of five successive calls for $40,000 each at 50 
cents per share, so that with the $25,000 that Messrs. 
Douglas and Tener themselves furnished, before they 
asked their friends to come in, there was $225,000 avail- 
able for exploratory work. 

In April of the same year an examination of the mine 
was made by Ira B. Joralemon, mining geologist to the 
Calumet & Arizona Mining Co. In his report Mr. 
Joralemon said that he would expect to find good sul r 
phide ore at a moderate depth below the leached and 
mineralized material on the 800-ft. level. He suggested 
that "the leached and crushed area in the Little Daisy 
might be part of a shear-zone, like that in which the 
great orebodies of Jerome occur. While the result of 
the work is a gamble, there is chance of finding a mine 
worthy of being compared with the United Verde." He 
concluded by stating: "I think the chance is worth 
taking. ' ' 

This advice justified a group of men in spending 
money that they could afford to lose. It confirmed the 
previous opinions of Messrs. Burger and Atwater. Mr. 
Joralemon received some shares in part-payment for his 
report, but took his profit prematurely when they rose 
to $6.50. Here I may anticipate by saying that the 
shares rose to $45 when the wonderful orebody was un- 
covered on the 1400-ft. level. Before that consummation 
was reached, however, several shareholders showed reas- 
onable conservatism, or 'cold feet,' as you will, and sold 
out almost as soon as they could get back the money they 
had put in. However, most of the original subscribers 
held on, becoming rich men, if they were not rich 
already. Captain Hoatson persuaded a number of his 
friends in Michigan to buy stock and I doubt not that

he increased his personal popularity thereby. Most of 
those that were too 'sane' to go into the ' gamble ' are 
very sorry indeed, and I fear that some of them may 
smile engagingly at the next 'wild-cat' that grins at 
them amid the Arizonan cactus. But I am far ahead of 



Jerome Verde company, under an option whereby the 
two properties were to be Oonsolidated if ore was found. 
Under this agreement 2760 ft. of exploratory work was 
done on the 800, 1200, and 1400-ft. levels, without pro- 
duetive result. The search for ore in the U. V. X. ground 




Fig. 3. plan of the it. v. x. workings, nombees indicate the order in which the work was done 



my story, the most important part of which remains to 
be told. 

In June 1913 a new shaft, called the Edith, after 
Miss Edith Tener, was started at a point 1900 ft. east 
of the first, or Little Daisy, shaft. This new shaft 
penetrated 180 ft. of lava, 400 ft. of limestone, 90 ft. of 
sandstone, and then reached the schist at 570 ft., which 
was equivalent to the 800-ft. level of the old shaft. A 
cross-cut was extended to the Main Top claims of the 



likewise proved disappointing. It was decided to sink 
200 ft. deeper, to the 1400-ft. level, and to cross-cut into 
the Main Top ground at this level, also by request of the 
Jerome Verde company. No ore was found. By Sep- 
tember the $225,000 of working capital had been spent 
and it became necessary to call upon the U. V. X. share- 
holders to subscribe for their proportion of additional 
stock at $1 per share. This they did unhesitatingly. 
The issue, however, was previously underwritten by 



16 



MINING and Scientific PRESS

Messrs. Douglas and Tener. Thus $50,000 was raised 
by the sale of treasury stock. The company was capi- 
talized at 1,500,000 shares of 50 cents, making $7,500,000, 
of which now $525,000, or 1,050,000 shares, had been 
issued. The old company had 500,000 shares of $10 
each, and of these 380,000 had been issued. "When the 
re-organization was made by Messrs. Douglas and Tener 
they exchanged shares with the former stockholders, thus 
accounting for 380,000 shares. They received 170,000 
shares as the profit of the promotion and of this amount 
they paid some of those that had helped them in the 
deal. They bought 50,000 shares at par, paying $25,000 ; 
they placed 400,000 shares at par among their friends, 
thereby raising $225,000 for working capital ; and 
finally they issued 50,000 treasury shares at $1 for fur- 
ther working capital. Thus 1,050,000 shares had been 
issued. No ore having been found in the Main Top 
ground of the Jerome Verde, that option was dropped 
in June 1915. Meanwhile all the available funds having 
been exhausted, including the last $50,000 obtained from 
the sale of the 50,000 treasury shares, Messrs. Douglas 
and Tener, not wishing to ask their friends to take more 
treasury stock, advanced $25,000 personally in the fall 
of 1914, and concurrently they engaged the services of 
one of the foremost geologists in the country to examine 
the mine and to show them where they had erred in 
looking for ore and to give them such advice as might 
haply lead them to find something before abandoning the 
entire project, which at that time seemed doomed. 
After a thorough examination, the distinguished geolo- 
gist, whose name is purposely withheld, condemned the 
mine and strongly advised his clients to cease operations. 
This opinion was so strong and stated in such positive 
terms that the management felt relieved of a great re- 
sponsibility and appeared justified in stopping work. 
As one of the principals says: "The position looked so 
bad that all further work seemed useless; it appeared 
time to gather up what salvage there might be, and close 
down the mine, swallow the loss, and forget it." How- 
ever, as the Cornishman says, "Never abandon a drift 
until you have driven 20 ft. farther. ' ' The management 
persevered a little longer, and in December a cross-cut 
being driven toward the centre of the U. V. X. ground 
from the main 1200-ft. level, connecting the Daisy and 
Edith shafts, cut five feet of 45% copper ore. This 
proved to be part of an orebody 120 ft. long and reach- 
ing a few feet above the 1100-ft. level. Prom this orebody 
about $600,000 worth of ore was mined during 1915. The 
prospect had become a mine, but its resources had only 
been touched. A drift was started on the 1400-ft. level 
to intersect the continuation of the ore discovered on the 
1200-ft. level, but it went beyond the point where ore 
was expected without finding anything. No cross-cut- 
ting was done until January 191*6 because a heavy flow 
of water had been cut south of the ore on the old 1200-ft. 
level, which at this time was not drained. It became 
necessary to install pumps at the 1400-ft. station and to 
provide bailers. The exploratory drift extending under 
the upper orebody had been stopped in a kaolinized rock, 



which encouraged expectations. This point was 850 ft. 
south of the Edith shaft. See map, Pig. 3. As soon as 
the pumps were in place, a cross-cut was driven both 
east and west in the hope of cutting the north end of 
the high-grade ore uncovered on the 1200-ft. level. Both 
of these cross-cuts drew a blank, for, as was shown later, 
the orebody had taken an abrupt dip westward at a 
point 60 ft. below the 1200, so that the cross-cuts were 
too far east. The next cross-cut eastward was started 
100 ft. south and found nothing, but the third (now 
labeled 1408) cut 16% ore when it had been advanced 
40 ft. from the drift, and it continued in ore for over 
200 ft. The main drift was extended into the orebody 
and cross-cuts were driven at intervals of 50 ft., proving 
a new orebody that reached to within 180 ft. of the 
Plorencia side-line, which is the south-eastern boundary 
of the U. V. X. property 5 ; indeed, the south-eastern end 
of the orebody reaches to within 30 ft. of that boundary. 
This, of course, was not the orebody cut on the 1200-ft. 
level, but a new and much bigger orebody, as the map 
shows. The smaller orebody discovered on the 1200-ft. 
level corresponds to the one known on the 1400-ft. level 
as the 1407, which was opened up subsequently by ex- 
tending the first cross-cut run in a westerly direction. 

On the 1400-ft. level the main orebody has an extreme 
width of 260 ft. and a length of 440 ft. It covers 62,400 
sq. ft. One ton of ore occupies 7 to 7J eu. ft. The upward 
termination of the main orebody is at 1240 ft. The ore 
is chalcocite, of secondary origin, of course. When I 
first saw a carload of it, just off the cage at surface, it 
looked like bituminous coal; it blackens the fingers. 
That carload assayed about 40% copper or as much as 
the concentrate made laboriously in the Miami and In- 
spiration mills. Indeed, it is a concentrate made by 
nature. In April 1917 the mine produced 4390 tons of 
38% ore and 7029 tons of 26% ore, containing therefore 
6,991,480 pounds of copper, worth $2,167,358. The pri- 
mary ore succeeds the secondary somewhere between 
1500 and 1600 ft. Between 1250 and 1500 ft. there is 
estimated to be 2,000,000 tons of 15% ore, representing 
600,000,000 pounds of copper, to be produced at a cost 
of 7c. per pound, leaving a profit of 10c. per pound, even 
if the price of copper averages no higher than 17c. dur- 
ing the period of exploitation. Thus a profit of $60,000,- 
000 is indicated. Experience in the United Verde shows 
that the primary ore averages 5% copper, and vertical 
development in that mine reaches to a depth of 1500 ft. 
in the schist. The U. V. X. may obtain 5000 tons of such 
ore per vertical foot, so that 1,500,000 tons of 5% ore, 
equivalent to 150,000,000 lb., is calculable. This ore, if 
exploited at a cost of 8c. per pound, would give another 
$13,500,000 in profit. The management assumes no re- 
sponsibility for any of these estimates. I give them on 
my own responsibility, as an essential part of the story. 
There should be enough rich ore to last for eight years 
and during this period there will be ample opportunity 
to ascertain the further riches of the mine. It is not

likely thai the output of the mine will consist only of the 
richer ore until all Of it has been exhausted; <m the con- 
trary, reasons, economic and technical, will prompt an 
admixture before smelting. Therefore 3,500,000 tons of 
10',' ore may he taken as more nearly representing the 
assured resources. 

Rich as it is and splendidly productive, the U. V. X. 
is a little mine; as measured in tonnage it makes a small 
output compared with the big low-grade disseminated- 
copper mines in other parts of Arizona. The Inspiration 
produces 20,000 tons per day of $9 ore; the U. V. X. 
produces only 300 tons of $150 ore, or $45,000 per day. 
This is a wonderful output to be made by a small base- 
metal mine. During 1916 the U. V. X. produced 36,- 
402,972 lb. of copper from 77,461 tons of ore, an average 
of 23.57o° copper, besides 2570 oz. of gold and 128,468 
oz. of silver, the total output being worth $9,949,918, of 
which $7,400,000 was profit. It had proved a glorious 
bonanza !

Concrete Fords for Crossing Streams 



The construction of concrete-paved fords in place of 
bridges across shallow intermittent streams with sandy 
bottoms is discussed in an article in a recent number of 
'Portland Cement.' Where the bed of the stream is 
considerably lower than the banks, or where the nor- 
mal flow of the stream is considerable, such fords are 
not recommended. 

In constructing a ford, 2 by 6-in. timbers should be 
used for side-forms and drag-guides. The top of the 
form should be placed at the average elevation of the 
sandy bed of the stream. The sand between the forms 
is then removed to a depth of 6 in. A trench is ex- 
cavated just inside the forms so as to provide a mold 
for a concrete baffle-wall. The trench is made deeper 
on the down-stream than on the up-stream side, since the 
former is more subject to wash. The baffle-walls are 
also carried across the ends of the ford. The ford 
should be made level at the bottom, and inclined, where 
necessary, at each end. The concrete is then placed. 
Triangular mesh or else f-in. twisted bars may be used 
for reinforcement. When required, some sort of apron- 
construction can be used. If the stream is not entirely 
dry under ordinary conditions, a concrete box-culvert 
can be combined with the ford. A plain concrete ford 
16 ft. wide can be built for $2.50 to $3 per lineal foot. 

A tank-steamer with no reciprocating machinery in 
the engine-room is being built in a shipyard on the 
Delaware. The propelling engine will consist of a low 
and a high-pressure turbine geared to a single pro- 
peller, a surface-condenser with a centrifugal pump 
driven by a turbine, two centrifugal hot-well pumps 
also driven by a turbine, and a rotary oil-pump for the 
turbine and gears, driven from the main gears. 

»The output for 1917 will have averaged about 4,000,000 lb. 
per month.

Mining at Butte 



By BEN F. EVANS 



For a short time prior to June 1917 the labor element 
in the Butte district passed through a period of unrest. 
This was caused by many unusual factors, namely, the 
general prosperity of the working people throughout the 
country, caused by high wages, the war crisis, numerous 
strikes, the pro-German propaganda, professional agita- 
tion of the I. W. W. type, and undesirable working con- 
ditions. All of these factors tended to bring the ma- 
jority of the miners to a common understanding. The 
unrest was brought to a climax by the fire in the Granite 
Mountain shaft, on June 9, when 160 men lost their lives. 
Two days later the Butte Metal Mine Workers Union 
was organized. This was inevitable and would have hap- 
pened in a short time even if there had been no accident, 
but the opportunity, when all the miners had so much 
in common to talk and think about, was seized by the 
labor-leaders. Demands were then drawn up and pre- 
sented to the operators. They included an increase of 
wages, changes in working conditions, abolition of the 
rustling card, committees composed of company repre- 
sentatives and union men not only to settle disputes but 
also to examine and make reports on underground condi- 
tions. These demands were not accepted. A strike fol- 
lowed. It can be added that many of the demands in a 
modified form were agreeable to the operators, but as 
modified they did not suit the union. 

During the period between June 11 and September 24 
the production of copper in the district was practically 
nil. Most of the miners had only enough men to keep 
up repairs and operate pumps. Miners left Butte by 
hundreds, as there was plenty of work in neighboring 
mining and construction camps, while many men went 
to the harvest and hayfields. Those with families, forced 
by circumstances to remain, received financial aid from 
the miner's organization, it is understood. Several local 
societies and business concerns contributed financially to 
the aid of the union. It is known that the organization 
also received help from organized labor outside the Butte 
district. During the early part of this period the crafts 
also were in an unstable condition. Some were, and 
others were not, in favor of affiliating the new union with 
this organization, and a strike was daily expected, but 
when it came to a vote the majority of the different 
crafts decided against affiliation. This decision was dis- 
liked by the members of the new union ; they maintained 
it was unfair, and based their claim upon the fact that 
an organization with a small number of men had the 
same power as one with a great many ; thus the decision 
was not representative of the men's feelings or sympa- 
thies. 

It must be understood that the miners' strike in Butte 



automatically closed the concentrators and smelters in 
the cities of Anaconda and Great Falls, as these plants 
depend upon the Butte mines for their ore. The mem- 
bers of the smeltermen's union were then easy victims 
for the strike germ, which pervaded the atmosphere at 
that time. 

About this time, or, to be exact, on the thirtieth day 
of July 1917, an agreement was entered into between 
the Anaconda Copper Mining Co. and the State Metal 
Trades Council, affiliated with the American Federation 
of Labor, through its local unions, which apparently 
satisfied all concerned, and went a long way in straight- 
ening out the labor situation. It conceded a rise of 25 
cents per day (beginning at $3 to $5 as the standard 
wages for different occupations) for each two cents rise 
of copper above 15c. per pound, as set out in a detailed 
schedule annexed to the contract. All over-time (includ- 
ing Sunday work) to be paid for at the rate of time and 
a half. A weekly pay-day is established. The company 
agrees to employ none except members of the affiliated 
unions. The State Metal Trades Council agrees to expel 
or discipline any rebellious 'locals' breaking the contract. 
The company absolves itself from settling any question 
of jurisdiction between local unions, leaving that to the 
Trades Council and American Federation of Labor. 

From the time the agreement went into effect no 
trouble of any consequence has arisen from the crafts, 
although there was a walk-out (but no strike) among 
some of the electrical workers. This was of short dura- 
tion. The fact that the Government set the price of cop- 
per at 23J cents per pound at this time would have 
naturally meant a reduction of wages, due to the sliding 
scale in use, based on the price of copper. The com- 
panies, however, decided that it would be better to main- 
tain the existing rate of wages, which was based on 
copper at 27c. per pound. This scale is to be in effect 
until the first of January 1918, 'at least. 

During the strike period, one noticeable condition was 
observed, namely, the absence of serious violence, such as 
ordinarily accompanies these strikes. The union men 
had an understanding that violence or lawlessness was 
not desired, and would not be tolerated. The one black 
mark in the entire trouble was the hanging of Frank 
Little, a well-known I. ~W. "W. leader and organizer. The 
presence of Federal troops in Butte during the height of 
the trouble and at the present time no doubt had a great 
influence upon all law-breaking people. The fact that 
wages were based on 27c. copper, that a great many men 
were tired of loafing and out of funds, and that no end 
was in sight for a final settlement, started the men back 
to work. The dearth of miners in the district at this 
time was noticeable.

MINING and Scientific PRESS 



January 5, 1918 



The smaller operators, particularly the zinc-producers, 
the Butte & Superior Mining Co. and the Clark interests, 
were the first to approach anything near normal ore pro- 
duction. The Anaconda Copper Mining Co., not being 
able to start all of its properties at once, and having to 
get its smelters into working order, was just a trifle 
slower in getting into its stride again, but soon took the 
lead in number of employees. As soon as it was gen- 
erally known around the country that the Butte mines 
were again working, the men gradually began to come 
back. All of this in spite of the fact that placards were 
circulated in many places advising the workers not to 
return to Butte, because the strike was still on. That 
the men wished to return was no more than to be ex- 
pected, as a great many who went away did so just to 
avoid trouble, and not because they had any particular 
grievance against the operators. It is also recognized 
among the miners that Butte affords the best living con- 
ditions of any camp in the country. There are no bunk- 
houses or mess-houses at the mines. The men find ac- 
commodations wherever they choose, and most of them 
have well-heated rooms, with hot and cold water, in some 
of the most modern blocks in the city, where they are 
close to any recreation they may desire. 

The Anaconda company has been starting up its 
largest mines as fast as the return of men warrants, 
until at this time, January 1, 1918, the company is em- 
ploying 94% of the normal force, and working most of 
the mines to capacity. This seems remarkable in view 
of the fact that so many men have left the city to join 
the colors. In the month of November the output of 
copper was 21,666,332 pounds, while the output of zinc 
was 3,955,707 lb. These figures afford ample evidence 
that operations are rapidly approaching normal. 

The high price of silver has helped generally. Old 
silver properties that had been lying dormant for the 
past 25 and 30 years suddenly sprang into activity. 
Practically all of the present large producers in the dis- 
trict showed interest in local silver properties. The de- 
mand for manganese for the steel industry went hand 
in hand with the silver development, most of the 'old 
silver mines having good surface showings of manga- 
nese. The Anaconda company is developing the Nettie, 
Orphan Girl, and Bonanza claims. The Butte & Su- 
perior Co. is working a group of claims in the silver dis- 
trict, the most important of which are the Germania, 
Tzarina, and Humboldt. The Clark interests are work- 
ing the Moulton, Anselmo, and Travona properties. 
The Butte-Detroit Copper & Zinc Co. has been mining 
manganese ore at the Britannia and concentrating it at 
the re-modeled Ophir mill, situated in the south-western 
part of the city. The Davis-Daly Co. has been doing 
extensive development work at the Hibernia and Mount 
Moriah claims, both old silver-producers. This work 
means a great deal for Butte's future as it enlarges the 
mining area about one-third and extends almost four 
miles south-west of its present productive area. These 
operations have caused much property to change hands, 
a good omen in the mining world. 



The North-Butte Mining Co. has been under great 
handicap as far as production was concerned. Much 
repair work had to be done at the Granite Mountain 
and Speculator shafts. At present the Granite Moun- 
tain shaft is b,eing concreted. This is the first work of 
that kind yet attempted in the district, and the result 
will be awaited with keen interest. The walls will be 
solid concrete and heavily reinforced with steel rods. 
A great many arguments have been advanced in con- 
nection with this work. The contention among some 
mining men is that this work will be more expensive 
and will not have any greater fire-resisting qualities 
than a cheaper construction. The heavy moving ground 
so common in the Butte district is liable to cause con- 
siderable trouble and make repairs run high. Ore is 
being hoisted from the Speculator shafts and shortly 
after the first of the year a normal production is ex- 
pected. The company is carrying on development work 
in the eastern part of the district, a new territory that 
has not been extensively developed. 

In conclusion, I would summarize recent changes as 
follows : 

On December 18 the Metal Mine Workers Union 
voted to call the strikes off, and return to work. Wages 
for miners before the trouble were $4.75 per diem, and 
at present are $5.25. Payment is based on the sliding 
scale with, a base of $3.50 per day when copper is under 
15c. and advancing 25c. for every 2c. increase in the 
price of copper. The rustling-card has been modified. 
A weekly pay-day is now in operation and has been 
received with much gratification by the miners. The 
Anaconda pays in cash, whereas the other companies 
pay by check as formerly. The weekly pay-day elim- 
inates the wage-scalper or assignment-shark. Formerly 
all employes were paid monthly. 

A great deal of work has been done for the safety of 
miners, and on precautionary measures in case of fire. 
This is shown clearly by extensive work that has been 
done in concreting the Tramway shaft, by the Anaconda 
company. This concrete is comparable to cement plaster 
on metal lath. The metal lath is stretched over the 
shaft-timbers and walls, then nailed in place. The ce- 
ment is then applied with a cement-gun. This is said 
to be fire-resisting, and when proved so, it no doubt 
will be generally adopted at all mines in the district. 
The same system is being used in underground stations 
and on fire doors. 

Ninety-four per cent of the normal working force is 
at work, a great deal of development work is going on 
in a long-forgotten portion of this mining district, and 
a general feeling of prosperity prevails, as is clearly 
shown by the increase of business, the successful flota- 
tion of the Liberty Loans, T. M. C. A., and Red Cross 
campaigns. When these were carefully examined it 
was found that the numerous small contributions from 
the mining men, not including the operators, when 
taken collectively, went a great way in making up the 
grand total, amounting to a local over-subscription of 
each allotment.

Mining Laws for Russia 



By HORACE V. W1NCHELL 



[Mr. Winehill was asked by the Ministry of Commerce 
and Industry at Petrograd to submit suggestions for 
framing mining laws, in Russia, based upon his ex- 
perience in the United States. He complied with the re- 
quest and we are enabled to publish herewith a part of 
his recommendations, believing them to be interesting to 
mining engineers in Russia and America.] 

We are accustomed to dividing mining laws and regula- 
tions into two parts: first, mining laws proper that con- 
cern the relations between the prospector and mine-oper- 
ator and the Government or private landlord, which de- 
fine the status of the prospector, establish method of 
procedure, protect him in his possession while searching 
for mines, and give him assurance of title when all the 
required conditions have been fulfilled and valuable min- 
erals discovered ; second, mining regulations concerning 
the operation of mines and the safety and health of the 
employees. It is my purpose to discuss here only min- 
ing laws as defined under the first class. 

Experience has shown that the prosperity of the min- 
ing industry and consequently in large measure, the pros- 
perity of a country, depends largely upon the character 
of its mining laws. If they are favorable there will be 
great activity in the operation of mines and great col- 
lateral development, such as the building of industrial 
communities, the construction of railroads and large 
manufacturing establishments. If the laws are not such 
as meet with the general approval of the prospector and 
the capitalist the mining industry languishes and the in- 
dustries of the country, which is thus compelled to rely 
upon imports from other lands, also fail to reach their 
highest development. As an illustration of this fact 
permit me to call attention to Chile in South America, 
which lies upon the west slope of the Andes mountains, 
and which, although not exceptionally rich in minerals, 
still, because of a liberal progressive mining code, has a 
mineral production valued at more than 140 million 
dollars per annum. Contrasting this with Argentina, 
which is a country of more than double the population of 
Chile, and which lies upon the eastern slope of the same 
mountains, and has equally great mineral resources, and 
yet, because of a difficult code of mining laws has a min- 
eral production of less than $300,000. As a further 
illustration of the great importance of the mining in- 
dustry permit me to state that the western half of the 
United States was developed first for its mines ; railroads 
were constructed, steamship lines established, and the 
large and important industrial communities of the West 
grew up around these mining centres and as a direct 
result of their activity. It is a significant fact that 60% 
of the business of all the railroads of the United States 



is derived from the products of the mines and quarries. 
Those facts and the further fact that metals are greatly 
needed not only in times of peaee, but in time of war for 
maintaining and defending a country's territory, are 
ample justification for a serious consideration of the 
question. 

Mining laws, in order to be operative and just, should 
be brief, simple, clear, and uniform. They should be 
brief and simple because they are to be read and inter- 
preted by individuals who have little knowledge of legal 
phraseology. In this connection permit me to point out 
that the Federal mining law of the United States, a copy 
of which I happen to have with me and enclose with this 
letter for your consideration, comprises only 28 articles 
and requires for its presentation but 9 printed pages. 
There has been considerable supplementary legislation 
and the Land Department has promulgated a consider- 
able volume of regulations for the carrying out of the 
terms of the law, but the law itself is ideal in its brevity 
and simplicity. The law should be uniform so far as 
possible in order that the prospector may understand 
clearly the requirements and may not unwittingly make 
mistakes and fail to comply with the provisions of the 
statutes. Thus, if there is a different law for the loca- 
tion of copper and gold and iron, and other metals, con- 
fusion will inevitably arise. 

The ideal mining law is one that protects the Govern- 
ment and the public interest on the one hand and at the 
same time protects the miner, and is so liberal in its pro- 
visions as to induce him to take the chances inevitable in 
the mining business and expend his time and money in 
search for and development of new properties. 

The Government should be protected, first, by requir- 
ing a reasonable amount of development in each year. No 
individual or corporation should be permitted to hold 
indefinitely large tracts of land for mining purposes 
without making serious effort to develop the same, and to 
work the mines on a reasonable scale. The Government 
should likewise require as nearly constant operation as is 
consistent with economic conditions. On the other hand, 
the Government should not attempt to prescribe rigor- 
ously how much ore should be produced every year nor 
at what price the product should be sold. It is manifestly 
impossible to thus control economic laws. The owner of 
a good mine will work his mine to its maximum capacity 
whenever he can dispose of its product, but when market- 
ing conditions are difficult and the price of metals is low 
so that the mine cannot be operated at a profit, he should 
not be required by law to continue to do so. 

In the third place, the Government expects and should 
receive some revenue from its mines in the form of taxes.

or royalty. By this I do not mean to imply that the 
Government should attempt to make large profits out of 
the operations of individuals or corporations. This has 
been a temptation in times past and has not worked out 
to the advantage of the community. A reasonable tax 
upon the product based either upon the valuation of the 
property or upon the net profit of the operation is always 
fair and cannot be objected to. But there are so many 
uncertainties connected with the mining industry that 
unless a large reward is possible the prospector and the 
miner will not exercise their activities. Furthermore, 
the benefits to the community and to the Government 
that arise from the development of mines in an indirect 
fashion is so much greater than that which could be de- 
rived by a heavy tax upon the mines themselves that it 
has now been generally accepted as true that a liberal 
policy produces the best results. 

The miner must be protected in exclusive and un- 
disturbed possession of his property. Many countries 
require an actual discovery of mineral in place before 
granting to the prospector any form of possessory titles. 
This practice is based upon ancient laws and customs. 
The more modern codes of mining law permit the pros- 
pector to stake his claim wherever he desires to prospect 
and protects him in his possession for a reasonable term 
of years so long as he continues in good faith to search 
for ore within his claim. The mining law of the United 
States requires a discovery before location, but this pro- 
vision of the law will probably be changed in the near 
future. 

The miner should have freedom of operation. He 
should not be unduly hampered by governmental restric- 
tions and regulations. It has been my experience that the 
mining engineers employed by governments and given 
authority over the operation of mines owned by individ- 
uals and corporations are not nearly so well qualified to 
direct such operations as the men employed for the pur- 
pose by the mine-owners. There is in the United States 
no such supervision of mining operations by Government 
officials or engineers. The only control exercised is in 
connection with regulations for safety and health. It is 
my understanding that in Russia mines owned by foreign 
companies are compelled by law to employ Russian engi- 
neers as managers. I know of no other country where 
such a law prevails. It is apparent from brief considera- 
tion that such requirements are not only distasteful to 
the owners, but actually a handicap upon the Russian 
mining industry, since mining companies of large capital 
and resources, with well-organized technical staffs, are 
not likely to view with favor the installation at their 
mines of men whose qualifications are unknown to them. 

The mine-operator should not be restricted in the 
marketing of his product. He should be permitted to 
seek the best market and make the best possible terms 
either at home or abroad. Referring once more to the 
United States I may be permitted to point to the fact 
that there is no limitation whatever upon the exporta- 
tion of its mineral products, either raw or manufactured. 
Contrast this situation and the consequent magnitude of 



American business in iron and steel products with that 
of Brazil, where there exist the largest deposits of high- 
grade iron ore known in the world, and yet a condition of 
industrial depression certainly attributable to at least a 
limited extenj to the refusal of the Brazilian government 
to permit the export of iron ore and other crude minerals. 
Look again at Sweden, where there exists one of the 
largest deposits of iron ore known today. This mine, at 
Kirunavara, contains enough iron ore to supply Sweden 
for more than 600 years, and yet the Government re- 
stricts its operation and production and thereby prevents 
extensive and large development. 

The fundamental idea that I have in presenting these 
few considerations is that no pound of coal, or iron, zinc, 
copper, or lead is of value until it is used. It does no 
one any good to keep it in the ground. It is useless to 
fear for the prosperity of generations yet unborn. They 
will look out for themselves. The art of metallurgy and 
the use of metals are so constantly changing that no one 
can foresee what will be required centuries hence. Con- 
sequently the nation which makes the freest use of its 
mineral wealth, throwing it open most liberally to the 
initiative of the world's miners, is the nation which in 
the immediate future will benefit most largely through 
the possession of these mineral deposits. American cap- 
ital, like the surplus capital from other countries, will 
go where it finds the best opportunity for employment 
and is promised the best return. Russian mines will be 
developed rapidly and extensively if the Russian laws 
are as favorable as those of other countries. 



The mineral output of Alaska in 1916 is valued at 
$48,632,138, being an increase of nearly 50% over the 
output of the previous year, which was $32,854,229. 
This increase has been due mainly to the activity in cop- 
per mining. The output of that metal for the year was 
119,602,028 lb., against 86,509,312 lb. in 1915. During 
the year 18 copper mines were in operation, nine in the 
Ketchikan district, six in the Prince William Sound dis- 
trict, and three in the Chitina district. The average cop- 
per content of the ore mined was 9.7% and the value 
of the combined gold and silver content was $1.60 per 
ton. Twenty-nine gold-lode mines were operated during 
the year, and the production was valued at $5,912,736. 
The average value of the combined gold and silver con- 
tent for all silicious ores mined in 1916 was $1.70. The 
value of the placer-gold production in 1916 was $11,- 
140,000, an increase of $660,000 over 1915. This in- 
crease came from the newly developed Marshall and 
Folorana districts. During the year 139 tons of metallic 
tin, valued at $121,000 was produced, chiefly from the 
York district, in the Seward Peninsula, where four 
dredges were operated, two of which worked on gravels 
carrying gold as well as tin. Much stream tin was re- 
covered from the placer deposits in the Hot Springs 
district. About 1500 tons of antimony ore, and about 47 
tons of scheelite concentrate, including a little wolfram- 
ite, was produced, mostly from the Fairbanks district. —

The Business of War 



By CHARLES T. HUTCHINSON 



i ommeroial United States doesn't know 'where it is 
lit.' and no wonder! Proprietors of big business enter- 
prises, presidents, managers, and what not, find them- 
selves do longer in authority. They are order-takers, 
not order-givers. Our Uncle Samuel is the one and 
only order-giver. Take thirty billion dollars, an in- 
conceivable sum of money, chuck it into the manufacture 
of all sorts of material utterly foreign to peace times, 
and it is not surprising that most people find themselves 
at a temporary loss to see anything farther ahead than 
the exigencies of the moment. 

Nevertheless, it will not take long for business to 
accustom itself to the new channels, although it may be 
rough going for a few months longer. As military 
needs become more clearly defined and standardized, 
and as requirements whether of men, ships, ordnance, or 
supplies become resolved into definite quantities within 
definite time, business men will be able to see what pro- 
portion of their product they may devote to maintaining 
their hold on former customers. As it is, the digestive 
apparatus- of commerce is trying to assimilate an alto- 
gether new diet. A certain amount of economic dys- 
pepsia, under these conditions, is not surprising. This 
condition is most pronounced in the great manufactur- 
ing districts. New York is the focal point, the nerve- 
centre of the War's industrial activities, while Wash- 
ington, only a few hours away, issues its mandates to 
the captains of industry. From one end of the country 
to the other everybody's doing it, and doing it with a 
will too. There are no half-way measures about the 
American manufacturer. "Any part, or all of my out- 
put is at your disposal." That is the way they talk, 
and that is the way they act. 

Some twenty years ago, we had a slight unpleasant- 
ness with Spain. In those days the country's need was 
regarded as the business man's opportunity. The ven- 
dor of obsolete transports, embalmed beef, shoddy uni- 
forms, and adulterated medical supplies clustered around 
headquarters like flies. An altogether different man is 
clustering today. His job is to give rather than to take. 
Those who have private means are working for nothing ; 
those who haven't are giving their services for a frac- 
tion of their earnings in civil life, while big and small 
industrial enterprises are, in large part, giving up their 
normal lines to devote their productive capacity to Gov- 
ernment needs. Of course, there is some profiteering. 
This is not the millennium. Such profiteering as there 
is, is relatively small and unimportant. There are para- 
sites who, possessed of some capital, are hoarding food- 
stuffs, especially such necessaries as sugar, and are ply- 
ing their nefarious trade through back alleys and behind 



elosed doors, selling in small quantities at famine prices 
l" those whom necessity makes an easy prey. If that 
class of profiteer could only be reported to the nearest 
office of the Pood Administration their activities would 
soon be stopped. Another kind of profiteer is going into 
the market, buying anything from scrap-iron to tin-plate, 
wherever he can find it, and taking his chances of being 
caught and his stock commandeered by the Government. 
This might be regarded as legitimate speculation, and so 
it is except during times such as these, when such ma- 
terials are so urgently needed by the Government for a 
more urgent purpose. 

Then there is the inn-keeper, whose activities are most 
pronounced in New York City. He deserves a para- 
graph to himself. His menus are decorated with the 
slogans of the Pood Administration. The victim, whose 
business compels him to visit the metropolis, reflects 
upon the all-pervading spirit of patriotism, until he sees 
the prices. That is the first shock. The second comes 
when he views the size of the portions. Apparently 
patriotism has enabled the Boniface at one time to in- 
crease his prices about 25% and decrease the size of por- 
tions another 25%. Glorious economy! Splendid pa- 
triotism ! It has been said that the saving in foodstuffs 
has aggregated some thousands of tons monthly, and 
elicited the commendation of the Pood Administrator 
himself. Here we have economy de luxe, while the ulti- 
mate consumer, scorned as usual, folds his tent and 
silently steals away, all the while trying to devise ways 
and means of camouflaging his expense account. 

The most stupid profiteer of the lot is the man who, 
placed on his honor in the execution of a war contract 
without fixed price, renders a bill carrying an exorbitant 
profit, with the thought that he won't be caught at it. 
Here is a case in point. The execution of a certain order 
for war material was placed with a manufacturer. In 
due course the work was finished. Then came the bill. 
It amounted to $37,000. The engineer who was acting 
as purchasing agent made an estimate of cost at $16,500. 
He called in art independent engineer, who estimated 
$16,700 as the probable cost. A Government department 
made an estimate based on the cost of duplicating the 
work elsewhere. Their figure was something under 
$17,000. All the documents and exhibits in the case 
were forwarded to the powers that be. Something is 
likely to happen to that contractor. 

Uncle Sam is an indulgent taskmaster, and will go to 
extraordinary lengths to help those who are 'on the 
level, ' but woe betide those who are not. Manufacturers 
who have turned their entire plants over to the Govern- 
ment are practically working on a cost-plus arrange-

ment, generally 10%. They can't lose money on this 
basis. All they are asked to do it to devote their best 
efforts to the production of perfect work and material 
in record time. Others who are taking work at fixed 
prices, find that the Government will aid them in obtain- 
ing materials at costs that would be impossible for the 
execution of private contracts. Then, again, contracts 
aie made based on the costs of labor and material at the 
time the contracts are executed, and subject to adjust- 
ment for any fluctuations that may take place between 
commencement and completion. What could be more 
fair? 

The Government has at its disposal any quantity of 
expert engineers, estimators, cost-accountants, and other 
specialists who are devoting their time to see that work 
is well done, and that the expense is in keeping with 
present conditions of labor and material. The Govern- 
ment will not knowingly pay for defective work any 
more than a private individual. 

There are two divisions of work in this country today : 
that which is directly contributory to the conduct of the 
War, and that which is not. The two basic industries, 
agriculture and mining, are in demand as never before. 
Lessons taught us by the experience of our Allies have 
been taken to heart. Governmental supervision of both 
these great essentials is already an accomplished fact, 
and while the administration of both is still in process 
of development in many details, yet the foundation is 
there and the rest will follow, it is to be hoped, with as 
few blunders as possible. 

Industries not directly or indirectly pertaining to 
war-needs will suffer, and in some cases, cease altogether 
until Victory perches on our banner. Work will be 
available for all willing men and women, perhaps at 
something other than that to which they have been ae- 
customed, but work nevertheless, and at record high 
wages. The labor problem is not to find work, but to 
make those work who don't want to work. 

Governmental assumption of power to fix prices must 
be extended to the fixation of those elements that make 
costs. The one element of uncertainty is labor; in fact, 
in the labor situation lies at once our greatest strength 
and greatest weakness. Enem3' propaganda is doing its 
utmost to attack us at this point, and it is to the credit 
of far-sighted labor-leaders like Samuel Gompers that 
thus far our productive capacity has not been materially 
impaired. If the elements entering into the cost of 
living can be held within reasonable bounds, so, in turn, 
can the question of wages be settled. As it is, wages in 
some trades would be attractive to bank presidents, while 
the clerks, book-keepers, salesmen, and other members of 
the unorganized 'submerged tenth,' between the upper 
and nether millstones of low pay and the H. C. L., are 
being ground to dust. 

What is more serious than wages is the tendency on 
the part of the workmen to limit output. This evil has 
been growing for years, and, according to some investi- 
gators, is worse now than ever before. To discover the 
cause involves an investigation of industrial conditions 



for many years back. In a few words, it is the effort of 
labor to fight one evil with another. Not so many years 
ago, capital operated on the principle of get all you can 
in exchange for as little as possible. Labor has adopted 
at least in p%rt this same principle. It is defenseless. 
Capital was the first to see the light. Whether this im- 
proved vision is due to higher morality, or whether it 
was forced by the growing strength of the labor-unions 
is of little consequence. It is sufficient to consider con- 
ditions as they are today, and that is that the capitalistic 
boss has been succeeded by the labor boss. • Neither is 
for the best interest of the Nation. Both represent the 
quintessence of selfishness — a selfishness that, in view of 
the country's present need, is treason. 

Some of the more advanced thinkers among labor- 
leaders, notably Samuel Gompers, are trying to stem the 
tide that they themselves started. Certain it is that con- 
ditions will not improve without the active co-operation 
of labor-leaders, great and small, who will join with 
employers in doing their utmost to point the way of duty 
and patriotism. There is even a greater need for the 
co-ordination of the forces of labor than of the Adminis- 
tration at Washington. Every man who calls himself 
an American should be made to realize his responsibili- 
ties in this great struggle of struggles. Every one of us 
is an integral part of the fighting force of the United 
States, whether he be clothed in olive drab, navy blue, 
or the unsightly but practical overalls of the workman 
or farm-hand. There is no five o'clock whistle on the 
Hindenburg line. There are no Saturday half-holidays 
at Essen. We have to defeat a nation in arms, and only 
by a greater nation in arms can it be defeated. 

Before long the war-after-the-war will receive atten- 
tion. It is receiving attention now from the more far- 
sighted business men, who can see farther ahead than the 
ends of their dignified noses. In the conduct of a suc- 
cessful business enterprise, brains and money are spent 
lavishly in the creation of that intangible something 
known as 'goodwill.' Many have tried to describe it, 
many have tried to capitalize it, and many have made a 
hash of it, nevertheless there is no such thing as business 
success without it. It is, in effect, the feeling of con- 
fidence and security that forms the invisible connection 
between those who serve and those who are served ; that 
depends, for its maintenance, upon continuous upkeep 
in good working order. It is the continuous upkeep of it 
that, in these days, is the sticking point. "How am I 
going to serve my old customers when the Government is 
taking 85% of my output?" said a distracted manu- 
facturer a few days ago. This question may be an- 
swered by reciting the policy, if it may be so called, of 
a prominent manufacturer of certain specialized ap- 
paratus, whose output for the next two years is all sold 
for war purposes. Inquiries for the purchase of his ap- 
paratus continue to come in at an even greater rate than 
before the War. Every inquiry is answered promptly, 
stating, on the all-important question of delivery, that 
the condition of the market will be carefully examined 
and a reply sent as soon as possible. Then he carefully

stitute Tbis information at band, be is able to serve 
bis customer, with apparatus other (ban that of his own 
manufacture, perhaps, but nevertheless the customer 
gets what be wants, and during these times will remem 
ber the man who did not desert him in bis hour of need. 
Where nothing can be done, the manufacturer's willing- 
ness to help counts for a great deal, and will not be for- 
got teu when the War is over, and everybody will be 
scrapping for orders in the good, old, time-honored way. 

The British manufacturer has learned his lesson, and 
is looking far ahead with an eye to what will come after- 
ward. The pictorial British weeklies carry practically 
as much advertising as they did before the War. It is 
mauy months since English manufacturers of automo- 
biles have been able to execute an order for any private 
party. Nevertheless they are giving as much space as 
before to setting forth the merits of their product, its 
improvements, its record in the war-zone, and soliciting 
orders to be filled when the War is over. The same is 
true of class and trade publications. Our London con- 
temporary is carrying as much, if not more, advertising 
space than before August 1914. 

There is nothing so dead as that which is forgotten. 
American manufacturers will do well to ponder over this 
statement and remember its truth. There is no excuse 
for lack of attention to civil inquiries, even if nothing 
can be done with them at present. The commercial 
fabric of the Nation must be preserved, and the holes 
patched up, for the trade and industrial war that is to 
follow the present physical struggle will be waged none 
the less bitterly and relentlessly from the fact that blood- 
letting will have ceased. 

Many manufacturers think they are worse off than 
they really are. A few inquiries or orders that for the 
present cannot be filled stampedes the herd. If the 
salesmen would put in their time trying to obtain what 
is wanted from any available source, they would earn 
their pay through the maintenance of their employer's 
goodwill, and lay up for themselves treasures untold 
when the day of reckoning comes, as it surely will. After 
it is over, this war will bring about a separation of the 
industrial sheep and goats. Those who regarded their 
temporary prosperity during war-times as a permanent 
institution will collapse like pricked balloons when Gov- 
ernmental orders have ceased, unless they maintain their 
connection as best they can with those whose business 
they formerly solicited so eagerly. "We are so well- 
known that they will surely come back to us" is a dan- 
gerous viewpoint. Customers are fickle jades, as a rule, 
and the continual receipt of the weekly bunch of violets 
is more effective than the occasional splurge of a box at 
the opera. Nothing is so irritating as unanswered mail, 
especially when the man whose letters are unanswered is 
sitting on a red-hot stove waiting, hoping against hope, 



thai a needed replacement will arrive and enable him to 
go on with bis work. 

•Metal milling is a war-necessity, and the machinery 
required should rank high in the rulings recently es- 
tablished by the Priority Board. Mining-machinerj 

manufacturers and dealers in supplies for mines are 
doing their best to meet t lie requirements of their custom- 
ers, while, at the same, building everything from ships 
to munitions for war purposes. Many factories are run- 
ning at 1007o load-factor for the first time in their 
history, while some are operating at as high as 200 % 
overload. Here is a chance for the real efficiency engi- 
neer. The cry is always for tonnage, and yet more ton- 
nage. In civil life the element of cost is paramount, In 
military life, it is the element of time. Cost is secondary. 
To hasten the end of the War a month, a week, a day, 
or even an hour, is to save untold wealth in human lives 
and energj'. 

One is proud of the way American business is putting 
its shoulder to the wheel. We know nothing definite as 
to the progress that has been made. There are military 
reasons why we should not. Nevertheless notes of cheer 
are heard above the din of battle. It seems that several 
submarines have gone to their final resting-plaee. Sev- 
eral ships flying the American flag are on the high seas, 
a novelty in maritime circles. Several American soldiers 
are now in Prance, and more are to go. Congress is in 
session, and may do something to the second-class postal- 
rate increase that will give the publisher a fighting 
chance. We have wheatless days, meatless days, and 
some of us are having sleepless nights. Nevertheless we 
are proud of our nation, the cause it has espoused, and 
are firm in the conviction that American brain, brawn, 
and dollars will supply the impetus that will give the 
finishing blow to Attila and his Huns. 



Japanese steel production is increasing rapidly. 
Through recent investigations by the Mining Bureau it 
is learned that the total producing capacity of Japanese 
steel mills was 888,000 tons, in round figures, at the end 
of August. During the first half of the present year 
289,000 tons of various shapes were produced exclusive 
of the colonies. Of this amount 200,000 tons came from 
the Government Steel Works. The Japan Steel Tube 
Co. turned out 22,000 tons; the Japan Steel Works, 
14,000 tons; the Kawasaki Dockyard Co., 12,000 tons; 
and the Kamaishi Steel Works, 10,000 tons. By the end 
of this year the products of those mills will reach at least 
570,000 tons net. Compared with the preceding year 
this is an increase of 50%. If this rate of increase is 
maintained, next year will see a further increase at least 
to 850,000 tons net. 



Platinum has been found in basic rocks in many 
parts of the world. Chromite is also common in similar 
rooks, and consequently it is sometimes accompanied by 
small amounts of platinum, in one ease, reported from 
South Africa, the amount being 1 dwt. per ton.

Joplin and the Komspelter Region 



By OTTO RUHL 



The past three months has represented a period of 
r< -adjustment in the zinc and lead districts of Missouri, 
Kansas, and Oklahoma: it has been one of the mcst 
severe from the point of view of strained credit, whole- 
sale closing down of mines, and even abandonment of 
some localities ever experienced, with perhaps the single 
exception of 1907. This is partly brought about by low 
prices and partly by gradually rising costs of produc- 
tion. The only relief in sight has been the transfer of 
operations from the low-grade properties to the high- 
grade, a relief often obtained at great sacrifice and dis- 
organization of working-forces. The transition from a 
prosperous industry in 1916 to a fight for existence in 
1917 has been marked by many struggles. Nevertheless 
the momentum of the highly prosperous times of 1916 
and the earlier part of 1917 has been such as to carry 
the annual production for lead and zinc to new high 
levels, and records have been made that can hardly be 
expected to be attained again for some time. Eleven 
months of 1917 shows an increase of 100,000 tons of zinc 
concentrate over 1916. The increase in lead concentrate 
is 11.835 tons. The increase in zinc was over 34% and 
the increase in lead 25%. The net increase in value for 
the two products is $5,000,000 on shipments alone, and 
to this must be added the surplus in the bins, totaling 
33.000 of zinc concentrate and 8500 tons of lead con- 
centrate. All of this increase was made in the face of a 
decrease in the average price of zinc concentrate. This 
decrease amounted to $9.18 for blende concentrate and 
$27.30 per ton on calamine concentrate. The increase in 
zinc prices therefore has come from the gain in tonnage, 
and not in price. The increased value of $19.11 for 
lead concentrate comes from both an increase in price 
and an increase in tonnage. 

The falling price for zinc concentrate and the rising 
prices of supplies and labor have steadily ground down 
the operators in sheet-ground until every item of profit 
has been extinguished and the balance, in many cases, 
is on the wrong side of the ledger. Only in a few in- 
stances, where units of operation were large and where 
the percentage of extraction was high, have they been 
able to hold out. Out of 150 mills in the sheet-ground 
district, around "Webb City and Carterville, one can 
count on the fingers of two hands those that have sur- 
vived. Even these may succumb : the end of the year 
may see further additions to the "plants closed-down or 
removed to other localities. This will wipe out a district 
that supplied 50% of the entire production of the 
region, a production that ranks as high-grade and that 
apparently cannot be replaced elsewhere in the United 
States. 



The impossibilty of replacing this output is recognized 
by all. The concentrates are free of any lead or contain 
extremely low percentages of lead, making them highly 
desirable by smelters engaged in the manufacture of 
sheet-zinc or for some classes of 'brass special' spelter. 
A large proportion of these concentrates would assay 
60 to 63% zinc, 0.005% lead, and 1% iron. Only mines 
in parts of Joplin and Alba Neck City would show the 
same degree of purity elsewhere in the district. On the 
other hand, throughout the year there has been a steady 
growth in a mill-product that runs 58 to 60% blende. 
1 to 1J% lead, and 2% or better in iron. It is evident 
from the trend of production that no such tonnage of 
high-grade ore can be expected from any part of the 
region now showing increased development. If any- 
thing, the grade is likely to be lower than higher. 

The only locality where high-grade ore is being de- 
vi loped is at Waco, north of the old Lawton mines. 
Here a number of new mills are yielding high-grade 
concentrates. The ore itself is not only rich but of good 
quality, and while the developments have not yet 
reached such a stage as to ensure a large production 
the mines already developed, together with the drilling 
now in progress, offer considerable promise for the 
future. The whole trend of development has been going 
toward the Oklahoma portion of the region, and the 
work already done may be rapidly extended north-east 
of Picher as far as Crestline, Kansas. One of the re- 
cent developments has been the testing of the Newton 
farm, east of Crestline, the results of which were so 
promising as to induce the American Metal Co. to pay 
$78,000 for the tract. The development by the Union 
Metals Co. at "Waco seems to be extending the produc- 
tive area south-westward and north-westward so that a 
possibility of a continuous line of operations is now 
within the realm of possibilities from Picher, Oklahoma, 
to Asbury, Missouri. A large number of drills are now 
being placed on the Missouri side near Asbury with the 
idea of testing that portion of the prospective mining 
area. The year therefore has seen a tremendous de- 
velopment of new territory covering portions of the 
States of Oklahoma and Kansas with the promise of this 
same extension of development into Missouri at the 
northern end of the line. 

Coincident with this prospecting and development 
work has been an era of mine investment that has not 
been altogether sane. The richness of some of the mines 
has induced the pyramiding of royalties. On top of the 
high royalties have come the gradual paying of higher 
prices for leases until there have been sales well above 
the million-dollar mark in single units, and some sales

nave been reported as high as $2,000,000 where com- 
binations of properties were made. It is doubtful 
whether many of the high valuations can be justified. 
Gradually there is growing a better sense of values, but 
this better sense has come rather from the shock of a 
falling ore-market and the realization that exploitation 
in the new district curtailed the highest cost of produc- 
tion in the entire region, and that conditions were grow- 
ing worse instead of better owing to the increasing cost 
of material and the growing inefficiency of labor. The 
latter is an extremely serious factor. It has been 
brought about by the unusually large number of new 
mines that have come into operation so quickly as to re- 
quire large numbers of laborers. The constant bidding 
of one concern for men has tended to raise the price of 
labor and to lower its efficiency. This condition has ex- 
tended even into the older settlements until it is no un- 
common thing to hear a mine-worker say at Webb City : 
"They will pay me $5 a day just to stay underground 
in the Oklahoma district, so why work up here." Con- 
ditions have gotten far beyond the control of the mine- 
operators in this respect, and while there is undoubtedly 
valid reason for paying higher wages at Piclier, there is 
none for the failure to receive an increase in actual labor 
performed. If the operations showed the same efficiency 
in the Picher area as they dp in the sheet-ground area 
of Webb City, the cost of production would not only be 
much lower than it is, but the production also would be 
greatly increased. 

The opening of the winter season totally disorganized 
both railroad and highway traffic throughout the new 
mining area extending from Commerce, Oklahoma, to 
Baxter Springs, Kansas. In the very midst of repairing 
the roek highway between Joplin and Commerce came 
18 inches of snow accompanied by cold weather. This, 
followed by thawing with heavy truck traffic over it, has 
been very disastrous and the highway is in an extremely 
bad condition. Very heavy traffic will be considerably 
delayed until such period of time has elapsed over a dry 
season to make possible the repairing of the damage 
already done. So far as dirt roads running off the rock 
highways are concerned, they have been impassable for 
the past ten days. This precludes any possibility of 
hauling coal to the mines or hauling ore away from 
them. These conditions have also seriously interfered 
with labor getting to and from the mining properties 
and their homes. Production here therefore suffered 
greatly for the past ten days and there is little hope of 
improvement for another fortnight at least. Both of 
the railroads into Oklahoma district are new. Their 
roadbeds have not been settled and the heavy snows have 
demoralized traffic over the railway until the efficiency 
is very low and little improvement can be expected here 
during this winter. In view of the prevailing conditions 
there can be little increase in output during the coming 
three months from the new district and it is doubtful 
if it will hold its own during that period if road con- 
ditions are not improved and a better supply of cars 



becomes available for coal-supply and the transport of 
ores. Already the mill Inns are full and it would be 

surprising if shipping i litions are improved suffi 

ciently in the next quarter to take care of this surplus. 
Unless this surplus is Bold operations can hardly be 

linaneed, except by one or two strong enneerns. This 
will act as a brake upon production during winter. An 
estimated output of 5000 tons per week from the new 
district during the next three months is believed to be 
conservative. The coming of the spring, however, will 
see a notable increase, if the market is favorable and 
fuel is available. 



A Substitute for Corrugated Iron 

The British, in their efforts to practice economy in 
the use of steel and iron, have developed and are now 
manufacturing a satisfactory substitute for corrugated 
iron and sheets. It is an asbestos-cement roofing ma- 
terial. During the last year a large plant has been built 
in England for manufacturing this product. The method 
of making it is as follows : After being finely ground and 
freed from extraneous matter the asbestos, which acts as 
the reinforcing agent, is mixed with portland cement in 
the proportion of about 1 to 6, and made into a paste 
with water. This paste is then taken to a machine of 
the paper-making type, where, on a large revolving 
drum, it is formed into sheets or felts. After the sheets 
have been trimmed to size, they have the corrugations 
imprensed on them. The important condition for this 
operation is to insure that the tops of the corrugations 
are as strong as the other parts of the sheets. Finally 
the sheets are subjected to a 'seasoning' process. The 
corrugations are made to the 3-in. pitch which is usual 
with corrugated-iron sheeting, not to the 2|-in. foreign 
pitch, and they can therefore readily be used to repair 
roofs of corrugated iron. One of the chief advantages 
claimed is their durability and resistance to climatic 
conditions, especially to an acid-laden atmosphere, which 
rapidly destroys corrugated iron. The sheets are also 
fire-proof and are poor conductors of heat. 

Brazilian manganese shipments, which, owing to the 
closing of other sources of supply, are now being made 
in large quantities to the United States, amounted to 
245,088 tons having a declared value of $5,733,000 dur- 
ing the first six months of 1917. The chances are that 
these will largely increase if the Brazilian railroads 
which carry the cargoes from the interior to tidewater 
and the conditions of South American shipping are able 
to cope with the increasing demand. 

The British Minister of Munitions has forbidden, ex- 
cept under permit, all dealings or proposals for sale of 
tungsten or molybdenite ores, and will fix maximum 
prices at which these ores may be bought or sold. Ap- 
plications for permits to export to allied countries must 
be made through La Commission Internationale de Ra- 
vitaillement, India House.

Manganese at Butte, Montana 

Manganese is abundant in most of the lodes at Butte, 
Montana, heretofore worked for silver and zinc. In an 
area of about five square miles that surrounds the prin- 
cipal copper mines on the north, west, and south-west, 
all the lode outcrops are black with manganese oxides, 
and in the workings that penetrate below the oxidized 
zone there are deposits of rhodochrosite and rhodonite, 
minerals containing manganese. 

A reconnaissance of the Butte district was made re- 
cently by J. T. Pardee of the U. S. Geological Survey, 
who reports that the development of manganese ores at 
Butte has heretofore been wholly incidental to the pro- 
duction of silver, zinc, and lead, in the ores of which 
manganese minerals are among the chief components of 
the gangue. Except a few small lots used for fluxing at 
the smelters, no manganese ore was mined for manganese 
prior to 1917. As ores containing less than 25% silica 
are rare in the district, the development of the lodes for 
manganese has lagged behind that in localities which 
produce ore of better grade. Systematic exploration of 
several of the larger manganiferous lodes has just begun, 
and search for pockets of marketable ore is being made 
in a small way by several lessees. 

The manganese ore is mostly oxidized and silicious, 
and its content of manganese ranges from 10 to 37%, 
but there are small quantities of high-grade ore, both 
oxide and carbonate. Of the higher grades of ore small 
bodies that contain 40% or more manganese in the form 
of oxides, chiefly pyrolusite, occur in most of the lodes, 
but this ore generally carries a rather high content of 
silica. At several places near the surface, however, 
there are pockets or lenses a foot or two thick and 10 to 
50 ft. long containing less than 15% silica and 40 to 50% 
manganese. Other small bodies that occur in certain of 
the lodes contain about 40% manganese and 5 to 25% 
silica. These are oxidized ores, but below depths of 40 
to 100 ft. the manganese oxides generally give place to 
rhodochrosite and rhodonite, which are found down to 
the limits of exploratory workings. The carbonate and 
silicate ores are generally intimately associated with 
quartz and with sulphides. 

The medium-grade ore occurs in bodies that contain 
20 to 37% or more of manganese. They range in length 
from 50 to 400 ft. and in width from 1 to 35 ft. Their 
minimum depths or pitch-lengths, as shown by the sur- 
face workings, range from 10 to 80 ft. Persons familiar 
with the deeper workings, which are not now accessible 
to examination, say that manganese oxides occur at one 
or two places to a depth of 200 ft., but that they gener- 
ally give place to pink manganese carbonate at depths 
of 40 to 100 ft. below the surface. 

Material containing less than 20% manganese forms 
the larger parts of many lodes. This material is prob- 
ably of too low grade to be considered ore at present, 
but it may be regarded as a possible future resource. 

Incomplete estimates of the manganese oxide- ore in 



the Butte district, in which Paul Billingsley and A. C. 
Grimes co-operated with Mr. Pardee, may be summarized 
as follows: 

Tons 

High-grade ore, low in silica 1,000 

High-grade ore, •silicious 1,600 

Silicious ore with 20 to 37% manganese 130,000 

Silicious ore with 10 to 18% manganese 270,000 

A common variety of the ore is rather coarse-textured, 
showing irregular interlocking masses of manganese 
oxides and quartz. Another variety is coarsely cellular, 
with criss-crossed partitions of pyrolusite in a skeleton 
or honeycomb of quartz. Ore of these varieties could 
perhaps be easily milled. A third kind, not so common 
as the others, is compact, fine-grained, and rather jas- 
pery, and all gradations occur between the three types 
mentioned. 

The main problems to be solved before Butte can be- 
come a factor in the manganese market under present 
conditions are (1) successful milling of the ores to pro- 
duce a low-silica concentrate, and (2) briquetting the 
concentrate or otherwise making it acceptable to buyers. 
Milling tests have already been begun, but the results 
have not been entirely satisfactory, owing chiefly to 
losses in the tailing by sliming. Methods of concen- 
trating manganese ore are now being studied by the 
United States Bureau of Mines. 

Labor has become the largest cost-factor in productive 
industry and seems likely to continue its relative in- 
crease. The ideal of industry is a laborer who is sober, 
efficient, and steady. The first is in progress of attain- 
ment by the advance of prohibition of the liquor traffic. 
Efficiency in the workman is attained through better 
management and training of the worker. Lost time is 
overcome by the prevention of accidents and illness, and 
through a great variety of means that bear indirectly, 
as indicated above, on the labor supply. Industrial-acci- 
dent prevention looms large in the public eye through 
the recent enactment of compensation laws, but as a 
source of lost time to the plant and lost wage to the 
worker it is much less important than illness. Health 
insurance is now being urged in many quarters, and if 
it comes about we may expect a transfer of emphasis 
from accident to illness prevention. Lost time through 
religious holidays and other personal activities, or in- 
activities, of the worker is much more important than 
either; their relative values being something like 1, 4, 
and 10, in most cases. The only practicable means of 
dealing with the latter seems to be the offering of a 
bonus, over and above wages, to the workmen who lose 
no time each month. The underlying purpose of person- 
nel work is to conserve the labor supply and decrease 
the net cost of productive labor. Personnel work is 
human engineering, it requires natural aptitude and 
special study and is not a field for the well-meaning 
amateur, especially the amateur who is unfamiliar with 
the peculiar problems of the industry in question. —

['nun Mining. — Tintic Drain Tunnel. — Tintic Output. 

John E. Brown closed a contract to haul a large tonnage 
of uranium ore in Dry valley to the railroad at Thompsons:', 

where a warehouse is being built to receive it. With a view 

to reaching the Cardiff contact as quickly as possible, the Tar 
Baby has left the fissure which has been followed for some 

time and is driving directly east. Fred McCoy, who has 

been engaged for a number of years in the development of his 
property at Beaver basin, on the north end of La Sal moun- 
tain, has formed the Panama Mining Co. Attention was 
drawn xo this property during the month, when Mr. McCoy- 
shipped a car of rich, copper ore to the Salt Lake smelters. 
The returns showed 274% copper and 37 oz. silver per ton. 
The property controlled by the new company comprises 2S0 
acres of valuable copper claims, situated in the Beaver basin. 
There are large bodies of low-grade lead ore which the com- 
pany intends to develop. The high-grade ore that has been 
mined is found at water-level in a well-defined vein. The 
company has a capital of $100,000, part of which will be spent 

in the erection of a small mill. The Central Standard 

Mines Co., operating in the eastern end of the district, has 
levied another assessment of Jc. per share. A shaft acci- 
dent at the Chief Con. delayed work during the early part of 
the week; one of the tanks used in hailing water caught in 

the shaft and tore out several feet of guides. Joseph S. 

Wing, of Springville, and associates are testing the oil-shale 
near Millfork at Spanish Fork canyon. They have located 
400 acres. Herman Harms, the State chemist, is now making 

an analysis of the shale. Satisfactory work is being done 

at the plant of the Tintic Milling Co., which treats 250 tons 

per day and produces 50 tons of bullion per month. Henry 

Barney, who is superintending the work at the Tintic drain 
tunnel, says that by the first of the year the machine-drills 
will be operating in the face of the tunnel. Work is proceed- 
ing by hand in a loose formation. A large engine will be 

erected by North Beck Mining Co. shortly. The equipment 
now in use is not heavy enough for deep work and conse- 
quently will be replaced with the larger hoist when the shaft 
reaches a depth of about 500 feet. 

McCarthy & Price is shipping three car-loads of manganese 
ore per week from the Chief Consolidated lease. The ore 
carries 38 to 39% manganese and is being shipped to the steel 
manufacturers in Pennsylvania. McCarthy & Price has suc- 
ceeded in opening a second deposit of manganese, which is 
about 200 ft. from the main discovery; it is possible that the 
ore will be found to be continuous between these two points. 
The deepest workings are less than 100 ft.. McCarthy & Price 
has leased another deposit of manganese in the West Tintic 

district from which shipping will soon begin. The annual 

meeting of the Grand Central Mining Co. will be held at 
Provo on January S when new officers will be elected and 
other business transacted. During the week ended De- 
cember 22 the mines of the Tintic district sent out 197 cars 
of ore compared with 206 the previous week. The shippers 
were Dragon Consolidated 51 cars, Eagle & Blue Bell 24, 
Chief Con. 16, Centennial-Eurake 14, Grand Central 13, Mam- 
moth 12, Tintic Standard 9, Victoria S, Colorado 7, Gemini 6, 



Gold Chain 6, Scranton 5, and Empire Mines 2. The com- 
bined shipments of the other nine mines makes the total of 

197 cars. The appearance of considerable water in the 

bottom of the shaft at the Eureka Bullion is believed to in- 
dicate that the bottom of the cave, which has caused a great 
deal of trouble during the last few months, is near at hand. 
Heavy talc is also appearing in the bottom of the shaft, along 
with large boulders of foot-wall material, containing manga- 
nese, barite, and iron. Small bunches of gray carbonate also 
are reported to be coming in and the management is con- 
fident that the work is approaching a big carbonate orebody. 
The shaft is down 640 feet. 

TORONTO, ONTARIO 

Dome. — Hollingeb. — McIntyre. — Kikkxand Lake. — Ntpissikg. 

The closing of the mill at the Dome Mines has been followed 
by the suspension of operations underground. Most of the 
men who have been laid off have remained in Porcupine and 
relieved the situation in other mines. Development, it is un- 
derstood, will be resumed at the Dome in January under the 
contract system and will include the sinking of the shaft to 
the 1500-ft. level. The directors anticipate that the mill will 
be started again in the summer to crush some 300,000 tons 
of $6 ore now in the stopes, which cannot be extracted until 
all the ore overhead has been broken down. This, it is esti- 
mated, will yield another 100,000 tons. The statement of 

the extent and value of the orebody recently discovered in the 
400-ft. level at the Millerton section of the Hollinger was re- 
ceived with some incredulity, and it was feared that the figures 
had been considerably exaggerated, but during a visit of the 
directors early in the month all doubts were set at rest. The 
vein has a width of 71 ft. with an average gold content of 

$28.60 per ton. Rich ore is being found in the lower levels 

of the McIntyre. The drift across the McIntyre Extension at 
the 1000-ft. level is in a large orebody in the Jupiter area, said 
to he 50 ft. wide and to carry about $10 per ton. An electric- 
haulage system is being installed on this level to facilitate the 
handling of the ore. Extensive diamond-drill operations are 

in progress. The Crown Reserve is energetically pushing 

the development of the Newray, where one vein 30 ft. wide is 
yielding upward of $10 per ton. The mill, which is being used 

as a testing plant, shows a mill-head of about $10. The 

McEnaney has tapped three rich veins in cross-cutting on the 
100-ft. level. Diamond-drilling will be undertaken to prove at 
depth a 16-ft. vein supposed to be an extension of the big 
Millerton vein of the Hollinger. 

The shareholders of the Teck-Hughes at Kirkland Lake 
have endorsed the proposal to raise funds for further develop- 
ment and the enlargement of the mill by increasing the capi- 
talization from $2,000,000 to $2,500,000. The new issue of 

stock will be offered to the shareholders at 30c. per share. 

The cross-cut of the Kirkland Porphyry on the 170-ft. level has 
been in ore for 32 ft.; the formation is similar to that of other 
mines in the camp. The shaft will be continued to the 300-ft. 
level. The Temiskaming, of Cobalt, is preparing to de- 
velop the Home and Grazelle claims adjacent to the Kirkland 

Lake mine. The Canadian Kirkland has put down two 

shafts, one of which, at 30 ft., is on a 16-ft. vein showing visible

gold. The Aladdin Cobalt has arranged to use the mining 

plant of the Sylvanite for carrying on underground work on 

the Burnside property, which it acquired recently. Most of 

the machinery for sinking the shaft at the Elliott below the 
300-ft. level is in place. The vein, which is probably a con- 
tinuation of the Kirkland Lake vein, is 12 ft. wide on the 
300-ft. level with ore of commercial grade. 

The Mining Corporation of Canada has started to develop 
the claim recently secured in the new camp of Rickard town- 
ship. A mining plant will be erected as soon as possible, and 
two diamond-drills are on their w-ay to the property. The 
surface showings are rich and the veins are of considerable 

size. At the Murray-Mogridge mine, at Bourkes Station, the 

drift of the 200-ft. level is in 120 ft., the vein continuing a 
good width with high gold content. The fault, found on the 
upper level, has been cut on the 200-ft. level. During No- 
vember the Nipissing mined ore of an estimated value of 
$305,572. and shipped products from its own and customs ores 
of an estimated net value of $331,196. The production for the 
year will establish a new high record, the total value of the 
output for the first eleven months being $3,018,280, as com- 
pared with $2,920,714 in 1913, the banner year in the com- 
pany's history. The shareholders of La Rose Consolidated, 

the holding company, with an American charter, have au- 
thorized its dissolution and the distribution of the assets of 
the company, consisting of the shares in La Rose Mines, the 
operating company, among the shareholders. The capital will 
be reduced from $6,000,000 to $1,500,000 and the exchange will 

be made share for share. The McKinley-Darragh has closed 

the re-grinding and flotation plant for treating tailing for the 
winter. It is proposed to substitute tube-mills for the pres- 
ent re-grinding equipment. The re-modeled mill of the 

Provincial is giving good satisfaction, the tailing from the 
dump yielding 12 to 14 oz. of silver per ton. The mine has 
an entensive tonnage of medium and low-g'rade ore blocked out. 



HOUGHTON, MICHIGAN 

Isle Roy ale. — Michigan. — Mohawk. — Osceola. 

The transfer of the railway service for the Mohawk and 
Wolverine mines, between the mines, mills, and smelters, from 
the South Shore subsidiary interests to the Copper Range in- 
terests, was concluded last week and the Copper Range now 
handles the business. This was one of the biggest railway 
deals that has taken place in the copper country for a number 
of years. Nothing more is heard of the rumor of the absorp- 
tion of the Isle Royale by the Calumet & Hecla. Now that 
the stock can be purchased in the open market for $21 per 
share, it would seem to have been a bad error in judgment if 
the Calumet & Hecla had agreed to pay twice that figure. 
Today Isle Royale is operating on a larger ore-tonnage basis 
than ever before, and is maintaining its underground openings 
substantially. With a normal market condition and a normal 
copper price and production price Isle Royale would be at- 
tracting as much attention as any other mine in the district. 

A 1000-ton test of the Michigan stock-pile showed 20 lb. 

per ton, not counting mass copper. It is believed that the 
rest of the stock pile will show just as good results. Under- 
ground openings in four different places are being carried 

forward, showing a good class of formation. Franklin is 

sinking to the 18th level on No. 2 shaft. The best ore is 
coming from the Pewabic lode to the north where a good shoot 

apparently is opening. Ore tonnage continues 1000 daily. 

Lessees of the Winona are getting out" 420 tons per day, mostly 
from King Phillip No. 1, but some from 3 and 4 Winona 
proper. The mill is handling 150 tons per day from South. 

Lake. At Mohawk, December likely will show an increase 

both in ore tonnage and in copper output. New ground opened 
in No. 1 shaft is better than it has been for some time past. 
Cross-cuts to the west show a series of small amygdaloid 



formations that are so good they are being investigated. 
Mohawk is shipping 2200 tons daily; Wolverine 1200. Wol- 
verine has re-modelled its shaft-houses to accommodate the 

50-ton cars now in use. The Phoenix is the only property 

of the Keweenaw that has been operating for several years. 
When work suspended a few weeks ago it was understood that 
the suspension was temporary. But the pumps are being re- 
moved, which looks like permanent abandonment. The 

most important news item of the week at any of the Osceola 
mines is the notable increase in ore output at the Kearsarge 
mines. Osceola now has a larger force than at any time 
during the year. For a week steady they got out 110 cars of 
ore per day, 3750 tons average from the Kearsarges; No. 3 
North Kearsarge is showing a steady increase. Locomo- 
tives for use underground at the Calumet & Hecla are helping 
to care for the trammer shortage, and the tonnage will soon 

be over 10,000 per day if present increase is maintained. 

At South Lake the ore is running 18 lb. per ton and the Butler 
lode, which is being stoped from three places, is showing a 
lot of nugget copper.

William N. Smith, general manager for the Vinegar Hill 
Zinc Co.. says the labor situation at present is much improved ; 
negroes have been introduced into the southern districts of 
the field and applied to common labor and shoveling at the 
mines, which has tended greatly to release the more experi- 
enced for the better classes of mine work. At the Meloy 

mine, owned and operated by the Vinegar Hill, electric mining- 
shovels are employed, which, it is claimed, are doing the work 
of 20 men. At the Jefferson mine, in the Hazel Green dis- 
trict, a newly developed property and now fully equipped, a 
heavy overflow has been struck and the pumps are lifting 
2100 gallons of water per minute. The mine is about drained 
and underground work will be in full swing before the first 
of the coming year. A new 800-gal. Pomona pump is being 
placed in the main hoisting-shaft. Double-compartment self- 
dumping cages are used for hoisting and li-ton cars will be 
used underground in connection with electric shovels. An 
exceptionally good showing is being made by the Vinegar Hill 
at both the Graham and North Unity mines, in the Galena dis- 
trict, where colored labor is largely employed. In the 

Mifflin district the Yewdall and Senator mines are operating 
steadily with about 100 men, making a daily recovery of from 
55 to 70 tons of zinc concentrate. The Rundell orebody, fully 
proved on adjacent lands by drilling machines, will remain 
undeveloped until market and cost conditions are more favor- 
able. The company is engaged in joint drilling operations 
with the Grunow Mining Co., on the east boundary of the 
Senator lease. Several drills are employed at the company's 
mines in the Benton district, but strikes have been few except 
on the Copeland lease near Shullsburg. 

The National Separating Co. of Cuba is handling 200 tons 
of raw concentrate every 24 hours averaging 29.32% of zinc. 
This yields 100 tons of finished blende ore assaying 60.54%, 
the bulk of which is sold in open market to the highest bidder. 
Shipments are made weekly to the Illinois Zinc Co., Grasselli 
Chemical Co., and the American Zinc Co. of Hillsboro, Illinois. 
A new Cottrell electric dust precipitator is being installed. 
Warehouses, machine shops, assay laboratory, and truck 
garage have been added to the big plant during the month. 
The Vinegar Hill Zinc Co. is giving employment to 500 men. 
The completion of an industry spur into the New Diggings 
district the first of December proved immediately beneficial 
to both the Meloy and Blackstone mines of the Vinegar Hill 
group and a big saving is effected in transportation of supplies 
and zinc ore.

MOHAVE COUNTY 

(Special Correspondence.) — It is announced that the Schuyl- 
kill Mining Co. has accepted an offer to take over the Ten- 
nessee mine and that operations will commence immediately 
to open the orebodies that pass from the Tennessee into the 

Schuylkill ground. A new company, the Standard Minerals 

Co., has taken over the Telluride Chief Mining Co. The ore 

is gold, silver, and copper, and carries some molybdenite. 

The 64 claims of the White Hills Mining Co. are to be auctioned 

to pay a debt of $1200. Active work has commenced on the 

Gold Road Bonanza. A station is being cut at the 500-ft. 

level. A consolidation of the Liberty Bell Gold Mining Co. 

and the White Chief Mining Co. has taken place. Machinery 
from the Liberty Bell has been moved to the White Chief and 
a cross-cut toward the vein at the bottom of the 125-ft. shaft 

will be driven. The Gold Ore is deepening its shaft another 

150 ft. in order to further develop the orebody opened up in 
the levels above. A tramway has been erected between the 
mine and the Gold Road mill, where its ore will be treated. 
The first cross-cut through the recently discovered ore- 
body of the Grey Eagle vein on the Tom Reed has been com- 
pleted at 180 ft. from the point of discovery, shoeing 20 ft. of 
ore. It is estimated that the December production will be 

$60,000. A splendid strike of ore has been made on the 

Morning and Evening Star mines 24 miles west of Kingman. 
Lessees on the Jamison mines in the Layne Springs sec- 
tion are shipping ore running as high as $100 per ton in gold, 
silver, and copper. While straightening out the shaft be- 
tween levels of the Walkover mine a fine body of ore running 
better than $50 per ton has been opened.

as a custom plant. It will handle 250 to 300 tons per day.- — 
Prospectors have located extensive scheelite deposits along 
the range of the Gunsight mountains, near Ajo. These de- 
posits, together with the recent discovery of gold placers in 
the same district, are causing a considerable rush. Ma- 
chinery for a mill to treat wolfram ores on the Canada Del 

Oro claims, 30 miles from Tucson, is being shipped. The 

Greater Ajo copper property, composed of 64 claims, will be 

taken over shortly by Eastern mining capitalists. The 

Stratton Copper Co., in the Old Hat mining district in the 
Catalina mountains, has been taken over by the Old Hat 
Mining Company.

YAVAPAI COUNTY 

(Special Correspondence.)— A rich orebody that is claimed 
to run 50% zinc, 6% lead, 2% copper, and 2 oz. silver has 
been opened at the Hillside mine. A standard drilling- 
rig is being shipped to the Chino valley for the Arizona Oil 

& Refining Co. Sulphide ore carrying 20 to 25% copper has 

been struck in the drift under the Maintop orebody, which is 
being driven preparatory to raising to the 1200-ft. level of the 

Jerome Verde. Work is to commence within a few days 

upon the Verde Tunnel & Smelter railroad from the United 

Verde crushing-plant to Jerome. A. G. Harbaugh has made 

an examination of the Verde Apex and Venture Hill Copper 
properties and, as a result, has taken half of E. L. Bartholo- 
mew's option on 100,000 shares of treasury stock. Money to 

develop these properites will be raised immediately. A 

group of 10 claims, called the Old Corkscrew, in Pine Flat, 
near Goodwin, has been purchased by J. A. Peacock of Fort 
Worth, Texas. The Circle Park Mining Co. will be formed to 

operate these claims. The compressor at the Abe Lincoln 

Copper Co. is in place; the 190-ft. shaft will be sunk to the 

500-ft. level. A larger hoist is also to be erected. J. R. Mc- 

Ewen and E. C. Evans have taken an option on the Belcher 

property in the Big Bug district. The Vesuvius gold mine 

is being developed by R. B. McMahon, the owner. The 

Copper Key property of 20 claims, in Black canyon, has been 
successfully financed. Sinking of a 500-ft. shaft will com- 
mence immediately. The Big Copper Chief just south of 

Bumble Bee has also been financed. New machinery is 

being erected at the Ada C. molybdenum mine north of 
Wickenburg, preparatory to sinking the 60-ft. shaft another 
300 ft. The ore is wulfenite and is reported as averaging 

5*% of MoO,. The gravity tramway from the Wildflower 

mine of the Crown King to the Bradshaw Development Co. 
mill is completed. The Grey Eagle mill in the Mayer dis- 
trict will be running as a custom mill shortly.

greater depth. Wales Palmer is the superintendent. Sink- 
ing is in progress at the Old Eureka property, the intention 
being to put the shaft down 1000 ft. below the 2165-ft. level. 
From the 1600-ft. level down the new company has enlarged 
the shaft to conform to three compartments above and good 
headway is now being made in the new ground. The old cross- 
cuts and drifts, particularly those on the 1200 and 1600-ft. 
levels, are being cleared and re-timbered. The Frakes and 
Goodman ranches purchased by the present company since 
closing the deal with Hetty Green for the mine will later be 
used for mill-site and tailing impounding area. T. Walter 
Beam is in charge of operations at this well-equipped property. 
H. DeC. Richards of San Francisco has recently been ap- 
pointed consulting engineer to the Central Eureka Mining Co., 
to work in conjunction with the superintendent, Fred Jost. 
Detailed mapping of the underground workings is being made 
for the better handling of the ore-reserve. Ore is being ex- 
tracted from the 3425, 3350, 2700, and 2500-ft. levels and 30 
stamps are kept in operation nearly, but not quite, paying 
expenses. A lie. assessment has been levied recently. During 
Christmas week, boilers, furnaces, and compressors have been 
repaired. 
Sutter Creek, December 29. 

NEVADA COUNTY 

(Special Correspondence.) — With the 60-stamp Empire mill 
operating at capacity and 20 stamps dropping at the Penn- 
sylvania mine, the Empire group is recording the heaviest 
output of its history and producing in excess of $100,000 per 
month. Splendid ore is said to be coming from the 2500-ft. 
level of the Pennsylvania and 4600-ft. level of the Empire, 
with late developments in the deeper workings particularly 
encouraging. More than 350 men are on the payroll. George 
W. Starr is general manager. At a point beneath the foot- 
wall of the Allison Ranch lode a new vein has been found 
on the No. 2 level of the Allison Ranch mine. The discovery 
was made in the south-west drift by lessees. The shoot av- 
erages 10 in. wide, assaying $30 per ton in free-milling ore. 
Careful prospecting shows the shoot persists to the seventh 
level, the deepest point to which the water has been lowered. 
Twenty-five men are working on company account, and sev- 
eral sets of lessees are active. The mill is running two shifts. 
W. Harvey, the superintendent, is proceeding with unwatering 

the shaft to the 1700-ft. level. The Grass Valley Deep Mines 

Co., composed of Nevada and Colorado people, has taken a 
bond and option on the Alaska-Ben Franklin group of quartz 
claims, situated seven miles south-west of Grass Valley. Ex- 
tensive work is to start immediately with Thomas W. Bosanko 
as superintendent. Some good ore has been exposed near the 

surface. Considerable activity is reported from Moore's 

Flat, above Nevada City. At the Gold Canyon developments 

are proceeding and good ore is exposed. W. H. Griffith is 
superintendent. A. Fitzgerald, the superintendent, is pushing 
work at the Fruitvale group. A large vein of profitable ore is 
reported exposed. 

Grass Valley, December 31. 

SHASTA COUNTY 

(Special Correspondence.) — The Mountain Copper Co. is 
preparing to erect a large cyanide plant at Minnesota station. 
midway between the Iron Mountain mine and Keswick. The 
plans are drawn and material for the building is on the 
ground. The cyanide plant will be used to save gold and sil- 
ver from ores that run high in those metals. Neeley 

Brothers' chrome mine, 17 miles w%st of Castella, is making 
shipments of chrome. Thirty-five mules pack the chrome 
three miles to the end of the wagon-road, where auto-trucks 
are loaded for completing the transportation to the railroad. 

Redding, December 27. 

(Special Correspondence.) — G. C. Taylor has taken a two- 
year option on the Donkey copper property, near Ingot. The 



option provides that a royalty of 10% shall be paid on ore 
running below and 157c on ore above $35 per ton. The prop- 
erty-was worked several months by the Mammoth Copper Co., 
and is stated to contain much ore of shipping grade. High- 
grade shipping ore has been uncovered on the 1000-ft. level 
of the Anchor mine, one of the properties comprising the 
Bully Hill group near Delamar. The deposit was opened 
through the Rising Star shaft. Steady shipments are being 
made to the Kennett smelter, and local stockholders state it 
is probable that a large flotation unit will be erected next 
spring, and possibly an electrolytic zinc plant, similar to the 
one operated near Kennett by the Mammoth Copper Co. All 
ores of this district carry a heavy proportion of zinc. Ship- 
ments of silicious copper-silver ore are going to Kennett from 
the Silver King mine, near Redding; the product comes from 
a dike 70 ft. wide and upward of a mile long. Considerable 
prospecting has been carried on and preparations are being 
made for deeper developments. San Francisco and Montana 

people are chiefly interested. L. E. Parker is manager. 

The Gardella Dredging Co. has practically completed No. 2 
dredge and expects to build two more in 191S. The holdings 
are situated on Clear creek, a few miles below Redding; No. 1 
dredge has been operating two years at an excellent profit. 
The owners plan to reclaim much of the dredged area and 

devote it to agriculture. J. A. Wilson and associates have 

arranged for extensive prospecting of dredging ground near 
Gas Point. The Shasta Dredging Co. has been working profit- 
able territory in the district for several years. The new area 
is owned by the Drew estate.

SISKIYOU COUNTY 

(Special Correspondence.) — New lessees are re-opening the 
Rancherie gold mine, one mile and a half from Hornbrook, 
and adding new machinery. The local power company is 
erecting a power-line from Henley to supply the mine with 

electricity. John Ritz of Etna who has been operating the 

Advance mine in the Forks of Salmon district has reduced his 

working force until the spring. John Traverse of Etna 

Mills is operating the Mercury American Co.'s mines at the 

head of Beaver creek. Much progress is being made with 

the new equipment erected on the Know Nothing gold mine, 
near Forks of Salmon, under the management of W. R. Beall. 

The Dewey gold mine, re-opened last summer after ten 

years idleness, is operating a ten-stamp mill and auxiliary 
machinery, driven with electric power. Recent development 

has uncovered a vein ranging from 10 to 20 ft. wide. The 

California Bar placer mine, near Croy, owned by the Vina Cali- 
fornia Bar Co. of Oakland, has resumed operations under the 
management of H. J. Croy. 

Hornbrook, December 27. 

TRINITY COUNTY 

(Special Correspondence.) — A vein ranging from 10 in. to 
3 ft. wide has been discovered by R. H. Bailey on Maple creek, 
about four miles from Junction City. The ore contains gold 
and a little platinum. Mr. Bailey states he has traced the vein 
3000 ft. and that much rich ore is exposed. Several claims 
have been located and development begun. Numerous placer 

mines were formerly working in this district. Prospecting 

of dredging territory continues active along the Trinity river 
and tributary streams, and much new exploratory work has 
started along the Salmon river and into Siskiyou county. The 
Pacific Gold Dredging Co., a Guggenheim subsidiary, is re- 
ported interested. Several fairly rich deposits have proved 
unsuitable for dredging because of presence of numerous huge 
boulders and heavily cemented gravel. The Pacific Dredging 
Co. attempted to work deposits of this character in Morrison 
gulch, but was forced to abandon the enterprise and move its 
dredge to a point near Carrville. Several companies are now 
trying to uevise a satisfactory method for economical working

COLORADO 

SUMMIT COUNTY 

At the new molybdenite mining camp of Climax, situated on 
the South Park line of the Colorado & Southern railway near 
Fremont's pass, the American Metal Co.. of New York, has 
almost completed a 250-ton concentration mill for the purpose 
of making a marketable grade of concentrate from the large 
body of low-grade molybdenite ore held by the company. Since 
August 1. about 130 men have been employed in the construc- 
tion of the mill, boarding houses, necessary mining structures, 
and two aerial tramways, and in doing development. The mill 
is situated on a spur track from the railroad at an altitude of 
11,300 ft. The mine is about a mile farther up the mountain. 
The deposit of 1% molybdenite ore outcrops about S00 ft. above 
the mill. The ore for the mill will be dumped into receiving 
bins at the mine, and from these will be taken by a two-bucket 
aerial tramway 500 ft. long, to crusher-ore bins at the foot of 
the hill. After being crushed the ore will be elevated to other 
ore-bins by a belt-conveyor, from which it will pass over a 
Leschen tramway 5000 ft. long to the receiving-ore bins of the 
mill. The ore will be ground in ball-mills and will then be 
concentrated in Callow and Janney flotation-machines, the con- 
centrate being de-watered on a Portland filter. The mill will 
have a capacity of 250 tons per 24 hours. The mill and bunk- 
houses will be steam-heated. It is expected that the plant will 
be In operation by the end of February. The large body of 
molybdenite, running from A to 16%, promises a steady supply. 
Recent sales of 60% molybdenite are reported as having been 
made at $4S per unit. 

The committee named by the Colorado legislature last 
winter, headed by Siewers Fincher of Breckenridge, to make 
a complete and exhaustive survey of the smelting industry of 
the State, in order to give the ore-producers information and 
data upon which they could figure with accuracy, and which 
would enable them in the future to deal intelligently in mak- 
ing contracts with the smelters, has completed its work. The 
investigation has been complete and thorough. O. R. Whitaker, 
a trustee of the Colorado School of Mines, was secured to take 
charge of the technical work. His report is replete with charts 
and tables. The law establishing the committee unfortunately 
did not provide funds sufficient for the publication of enough 
of these reports to fill the demand, but they will be made to go 
as far as possible and early applicants probably can be sup- 
plied. The Smelter Investigation Committee has offices in 
the Capitol building, Denver. 

TELLER COUNTY 

(Special Correspondence.) — Thrift or war savings stamps 
took the place of gold coins for Christmas donations to em- 
ployees by mining and leasing companies of this district this 
year. The second discovery at the 500-ft. level of the Em- 
pire State shaft has been made by the lessee, Yaksey & Co., 



on the rich Malonej vein. The Bhool opened up for LB ft. i" 
dale is making rich Boreeningl. In the core of the Malonev 
vein a BlX-lnch streak of lluorlle anil quartz earries larne 

crystals ol calaverite and Is good for 100 oz. gold per ton. 

Shipments have been resumed from the Wild Horse mine of 
i ted Gold Mines Co. on Hull hill. Carl Evans, superin- 
tendent, has opened up a strong body of milling ore at the 
500-ft. level of the Gleason shaft and is shipping two ears per 
week to the Golden Cycle Mining & Reduction Co.'s plant at 

Colorado Springs. A new and rich discovery has been made 

on the Shoo Fly, a Stratton estate property on Womack hill, 
just beyond the eastern boundary of this city, by Slmms All- 
baugh & Willis, lesees from the Stratton estate. At a point 
about 70 ft. west of the Hickman discovery and at a depth of 
about 75 ft. from surface, the lessees are mining between 2 
and 3 ft. of quartz carrying rusty gold and making screenings 

that will ship at close to five ounces gold per ton. A new 

lease covering a three-year term has been secured from the 
Free Coinage Consolidated Co. by L. F. le Brun of Cripple 
Creek, with whom is associated F. H. Phillips of New York, 
on 1300 ft. of the Wilson lode. The lessees are driving into 
the leased ground from the SOO-ft. level of the Lee shaft, giv- 
ing them 400 ft. of virgin ground under the Murphy, Mercer, 
Reed, and Van Tilborg stopes on the "Wilson, from which big 
money has been made by the different lessees named.

NEVADA 

CLARK COUNTY 

(Special Correspondence.) — Development of the main ore- 
body on the 700-ft. level of the Yellow Pine is being pushed 
vigorously. The orebody has been opened for over 200 ft. on 
its strike and shows shipping ore throughout. The winze 
from this level has cut, at a depth of 40 ft., an orebody nine 
feet thick, assaying 48% zinc. From the 900-ft. level cross- 
cutting is advancing to tap the main vein and should attain 
its objective within three months. The mill is running at full 
capacity and tailing from the slime pond is being dried and 
shipped. In the present year dividends totalling $360,000 have 
been disbursed. There remains in the treasury $100,000 in 
cash, and $75,000 represented by Liberty bonds. The Man- 
ganese Association has started shipments to Salt Lake, and 
expects soon to be in a position to produce 200 to 300 tons of 
ore per day. Numerous ore-buyers are in the district, and 
several claims adjacent to the producing group have been 

examined. The property is a few miles from Las Vegas. 

The winze from the adit in the Oro Amigo is down 65 ft. and 
has been in ore for 35 ft. The shoot ranges from 8 to 14 in.

the ore together with, a little platinum. Preparations are 
being made tor occasional shipments, and tor further develp- 

ment. Sam Yount is manager. Dedrich Bros, have made a 

promising discovery on the property of the St. Anthony 
Mining Co., near Goodsprings. The vein ranges from 12 to 
24 in wide and occurs in ferruginous formation. The ore is 
stated to assay 45% copper in the form of copper glance. 
Goodsprings, December 23. 

ESMERALDA COUNTY 

(Special Correspondence.) — The second payment on the in- 
debtedness of the Florence-Goldfleld company has been made 
to creditors, and Harry B. Clapp, the receiver, expects to 
make the final payment on or before January 15. Immediately 
upon recovering control of the property the owners will ar- 
range for re-organization of the company and resumption of 
work, according to advices received here by stockholders. The 
Dell Hammond-Charles Taylor lease is developing rich ore 
and reports net earnings of $15,000 in a brief period. A num- 
ber of lessees are opreating on Florence ground with good re- 
sults. The cyanide and flotation units of the Goldfield Con- 
solidated are treating approximately 32,000 tons per month, 
divided about equally between mine-ore and tailing from the 
old mill-pond. In October, 15,975 tons of the latter was re- 
treated, netting $5800. In the same period 15,900 tons of ore 
yielded net profits of $15,043, making a total earning of 

$20,843. Developments on the 1350-ft. level of the Grizzly 

Bear are claiming interest, with ore ranging from $9.60 to 
$10.35 per ton coming from two working-faces. The orebody 
recently discovered in the Aurora Consolidated, at Aurora, is 

stated to be developing satisfactorily. The winze from the 

main drift on the 880-ft. level of the Jumbo Junior has ex- 
posed a shoot 18 in. wide, reported to assay $50 to $150 per ton 
in gold, silver, and copper, with silver predominating. The 
discovery was made near the hanging wall and prospecting is 
proceeding to determine extent of the shoot. A shipment is 
being prepared. Connections have been established between 
the northern workings and the main south drift of the Ke- 

wanas mine. J. J. Jordan and Edward Yeiser have appealed 

to the Supreme Court from an order issued by Judge Walsh, 
restraining them from disposing of their interest in the Life 
Preserver group of gold claims at Tolicha. They are said to 
have agreed to sell the property to Zeb Kendall for $120,000. 
Dave Ward secured the restraining order, claiming he held a 
one-third interest. 

Goldfield. December 22. 

MINERAL COUNTY 

(Special Correspondence.) — Development on the 250-ft. level 
of the Nevada Rand, near Rand, has proved encouraging, with 
the new vein developing well; 20 tons of ore averaging $100 
per ton has been shipped, and an 8-in. shoot assaying $1675 in 
silver and gold has been uncovered. The management is pre- 
paring to drive from the 350-ft. in expectation of cutting the 
vein at this point. A mill is planned, as upward of 35,000 
tons of $15 ore has been blocked out. The Reservation dis- 
trict, a few miles from the station of Reservation on the Gold- 
field branch of the Southern Pacific railway, is attracting con- 
siderable attention, with silver-lead, gold, and copper deposits 
occurring. The Packsaddle is being placed in shape for pro- 
duction, and sinking of a new shaft at the Reservation Hill 
will start shortly to open promising ore in new territory and 
avoid the water which forced suspension of operations in the 
old workings. The June Bug is active, and the Sebastopol is 
being placed in shape for steady work. The Mountain View 
has produced some good ore this year; the mill has been in 
operation for several months. 

Luning, December 29. 

(Special Correspondence.) — The Calavada Copper Co. has 
erected an air-hoist on the 1000-ft. level of the main shaft and 



will continue sinking the winze, which is now down to the 
1100-ft. point, to the water-level; this, it is expected, will be 
reached in the next 200 ft. It is believed that the primary 
sulphides will be found at the water-level and also secondary 
enrichment from the re-deposition of the values that have 
been leached <rom the oxidized ores above. High-grade ore 
has been found from the surface down and at the 1000-ft. 
level there is ten feet of oxidized ore averaging better than 
15% copper, with residual bodies of chalcocite that go 50%. 

The Kirchen Mines Co. is shipping from three ore-shoots 

in the lower adit of the St. Patrick mine, the third having 

been opened during the week. The three new finds which 

were recently made in the mines of the Pilot Copper Co. are 
holding their own as development proceeds. The first two 
were in the Champion mine, at the 150-ft. level, and the third 

in the big vein of the Anderson mine. The face of the drift 

on the electrolytic claim of the Congress Copper Co. is still

in ore that averages 5%, while the adit on the N'eversweat 
claim is making good progress and will soon reach the down- 
ward extension of the rich orebody that was glory-holed at 
the surface. 

The last two carloads of ore shipped by the Pilot Copper 
Co. from Luning returned $1132 and $1209, respectively, after 
deducting freight and treatment charges. Three important 
finds were made during the week. The first was in the Cham- 
pion mine in a raise from the 150-ft. level where a hitherto 
unknown vein carrying 3 to 10% copper was cut. The second 
was on the same level about 500 ft. distant. In a cross-cut 
going through the heart of a low-grade orebody a face of 
carbonate ore 7 ft. wide and S ft. high was exposed which 
averages 4% copper. The third was in the Anderson mine 
where the hanging wall of a 28-ft. vein was reached. The 

last 8 ft. of this .vein averages better than 4*%. In an east 

drift on the Electric claim of the Congress Copper Co. the 
last 26 ft. has been in ore averaging 5%. On the company's 
Neversweat claim an adit is being run to get under the old 

glory-hole from which so much rich ore has been shipped. 

At the Luning Idaho mine, in addition to the usual work, an 
adit has been started in Erickson gulch which will tap the 
orebody developed in the Stockham adit at 100 ft. greater 
depth. It is probable that this can be run in ore the entire 

distance. The Kirchen Mines Co. is maintaining steady 

shipments of high-grade ore from its St. Patrick mine, the

WASHOE COUNTS 

(Special Correspondence.) — A new large Cameron station 
pump lias been ordered tor the Xixon-Nevada mine, ami as 
s it is in place a winze will be started on the No. 1 
vein at B point about 100 ft. from the cross-cut. Here is an 
Dnusuall] good showing, With bunches and streaks of almost 
pure chalcoclte in the oxidized ores. Stoping in good ore is 
in progress on the No. 2 vein, the present workings being 
about 75 ft. from the cross-cut. II is evident that the niin- 
sralization from the Xo. 4 vein extends much farther into 
the wall-rock at the lower level than from the other veins. 
The cross-cut still shows lots of iron and copper stains, but 
recent surveys show that it will have to be run considerably 

farther before the vein is reached. The drift on the No. 

1 vein is now out 350 ft. from the cross-cut and a raise is to 
be put up near the face to explore the new orebody. This is 
the second ore-shoot that has been found in the north drift, 
the first being 200 ft. long and the ore high-grade. The north 
drift on the No. 2 vein is out 100 ft. and is also in high-grade 
ore. The main cross-cut still shows copper stains and small 
stringers, but has not yet cut No. 4 vein. The new six-foot 
vein which was recently opened by surface trenching looks 
especially good.

SOCORRO COUNTY 

(Special Correspondence.) — The Oaks Co. is working through 
its new main Central shaft. Levels are being run to connect 
with the lower working of the Maud S. mine and as soon as 
these are completed ore will be extracted through this shaft. 
Development and ore-breaking continues in the Pacific, Maud 

S., and Eberle mines. Material is coming in rapidly for the 

new Socorro Mining & Milling Co.'s plant. Construction work 
is progressing at mill and mine. It is understood that the 
mill will have a considerably increased capacity and will be 

modern in every way. This has been a big year for the 

Mogollon district. Tonnage in the various mills has been up 
to capacity and, while the figures are not yet available, the 
total production will be large. Development in the lower 
levels of some of the deepest work in camp has opened up 
good ore and the mineral discovered within the year and the 
new mines opened, places the Mogollon district well in the lead 
of the silver-gold camps of the South-West.

OREGON 

JACKSON COUNTY 

(Special Correspondence.) — Harvey J. Sallee, who recently 
bonded the Barron gold mine east of Ashland from the Alton 
Mining Co. of Ashland, has closed down the mine for the winter 
and left for his Reed mine in Shasta county, California. He 
has spent $6000 in re-opening the Barron mine, but the late 
heavy rains have made the roads impassable between the mine 
and railroad. During the operation five car-loads of ore were 
shipped to the Mammoth Copper Co. smelter at Kennett, which 
assayed 1 oz. of gold to 20 oz. of silver, with some zinc and 
lead. The high-grade ore assayed $75 per ton in gold and 
silver, while the low-grade $10 to $15. There is 1000 ft. of 
drift in the mine, one main drift and some prospects. The 
lessee thinks well of the property, although it presents some 
difficulty in the way of economical operation Under the con- 
ditions this fall the haul to the railroad, a distance of seven 
miles, cost $5 per ton, while the difficulty of placing a mill at 
the mine is that water is only available six months in the year. 
Much progress is being made in developing and operating 



the Chisholm cinnabar mines. L2 miles north of Cold Hill. 
YV. l'. Chisholm, the owner, reports that he will put in crushers 
and concentrating machinery next spring to operate with his 

12-pipe furnace. L. F. McConlche, of Tacoma, representing 

people of that city, is developing the Buena Vista group of 
cinnabar mines, recently purchased from W. S. Webb of Med- 
ford. This property is just over the Jackson county line in 
Douglas county, and is an extension of the mercury-bearing 
dike that extends through Jackson county from California. 




PART OF OREGON 

The property will be fully equipped with furnaces next spring. 

Extensive work is being done at the Greenback gold mine 

in the north end of this county. The old equipment is being 
dismantled in order to erect new machinery during the coming 
season. The 7000-ft. aerial-tramway has been sold and is being 
removed to equip the State limestone-fertilizer plant at Gold 

Hill. The late rains have set the placer mines through 

southern Oregon and northern California in operation, and 
from present indications the coming season will be a success- 
ful one. Considerable attention will be given by the oper- 
ators to save platinum, which formerly went to waste.

Cross-cuts are proceeding in two directions from the bottom 
of a 175-ft. shaft in the property of the Silver-Antimony Min-

100 ft., has penetrated 40 ft. of mineral that is marked with 
ribbons of ore containing silver and copper, some of it in the 
native form. The east cross-cut, driven 45 ft., is directed at a 
body of silver and antimony four feet wide at the surface. 
The directors of the company are J. J. Wells, president; J. 
Kuntz, vice-president; and Harry W. Hoefer, secretary-treas-

source of the ore is a section of the vein IS to 24 in. wide on 
the 200-ft. level of the shaft workings. More or less rock 
becomes mixed with the ore in breaking, which explains the 
low grade of the product. The drift lacks about 200 ft. of 
attaining the point where ore of better grade was found on the 
level above. Operations are being confined chiefly to a raise 
from the 200-ft. level. A little ore is being broken in a stope 
started north of the raise. The advance of the raise, which is 
to be connected with a winze, is handicapped by water. Until 
the raise is completed and ventilation provided little work 
can be done on the new level. Fourteen carloads of 50 tons 
each were shipped to the Tacoma smelter in November. 

CANADA 

BRITISH COLUMBIA 
The strike of men employed by the Consolidated Mining & 
Smelting Co. at Trail, has been called off, according to a report 
from Trail received December 20. One thousand men, it is 
estimated, returned to the plant and the remainder will return 
as soon as places can be found for them. It is believed the 
Consolidated company will issue an order for the resumption 
of operations on its properties at Kimberley, Rossland, Bholt, 
and elsewhere in British Columbia, which were suspended 
when the strike was called on November 15. The number of 
men affected is said to be from 6000 to 7000, including those 
employed at Trail. The tonnage released is S000 to 10,000 per 

week, of which about 10% is from mines of Washington. 

The suspension was not total in mines outside of those owned 
by the Consolidated. Operations were maintained with reduced 
forces on several properties. A large tonnage of lead ore has 
been accumulated, but zinc ore was sold in the United States 
by several corporations in the interim. 



Obituary 



Fred Turrel Gbeene, mining engineer and geologist, was 
killed in a motor accident at Butte, Montana, on Christmas 
day. He was born at Brooklyn, New York, 43 years ago; he 
graduated from the University of Toronto in 1S93 and from 
the Michigan College of Mines in 1897. Immediately there- 
after he entered the engineering department of the Boston & 
Montana company at Butte, and a few years later he became 
assistant to Horace V. Winchell, then geologist for the Amal- 
gamated Copper Co., this association with Mr. Winchell con- 
tinuing to the end, for at the time of the fatal accident he 
was working with Mr. Winchell as a geological expert in the 
litigation between the Elm Orlu and Butte & Superior com- 
panies. His untimely death was a great shock to the mining 
community of Butte, where he had been socially prominent and 
generally liked as a sincere, honest, and thoroughly capable 
engineer. 

James W. Malcolmson died suddenly on December 26 at 
Kansas City, Missouri. He was consulting engineer to the 
Lucky Tiger Combination Gold Mining Co. at the time of his 
death and was largely responsible for the success of that 
enterprise, well known in Mexico as the El Tigre. He was 
educated at the Royal School of Mines, London, whence he 
graduated with honors in 18S9. During the course of his 
career, which was honorable and successful, he served as 
mining engineer to the Consolidated Kansas City Smelting & 
Refining Co. from 1893 to 1898, as manager of the mining de- 
partment of the A. S. & R. Co. in JV^xico from 1902 to 1909, 
and since then as consulting engineer to the Lucky Tiger 
Combination company, with headquarters in Kansas City. 
He attended the recent meeting of the Institute at St. Louis 
in October, when he appeared to be in excellent health and 
spirits. His sudden end will come as a great shock to his 
many friends, who will join in sympathy for his wife and 
family.

Samuel Montagu & Co. says: The negotiations of the British and United 
States governments with regard to the purchase of a substantial portion 



of the world's production do not yet appear to have reached i definite 
form. Items of news have been cabled from New York about tin- matter, 
but not of sufficient precision to enable a Judgment to be founded as to 
the effect of this important projected step upon the eastern exchangee and 
the future of Bilver. It is stated that the United States of America pro- 
duced 72.833.000 oz. in 1916. out of a world production of 172.. 383, 000. 
It is anticipated that the United States will turn out at least 75.000.000 oz. 
in 1917. so that with improved conditions in Mexico, the world's total may 
approximate 200,000.000 oz. for this year. Should, therefore, the original 
information be correct, and an amount of 100.000.000 oz. be acquired by 
the Governments for delivery in 1918. this would be equal to 50% of the 
world's probable production, while if only the United States output be 
purchased, it would be equal to about 37^%. The Department of Com- 
merce in America announced on November 28 that the silver exports during 
this year had amounted to $62,234,000. There has been a considerable 
shrinkage, namely. 147 laos in the Indian note circulation. As regards the 
reserves, the silver holding was reduced by 194 laos, but the gold increased 
by 47 laos.

The spot position for quicksilver is as bad as ever and little spot ma- 
terial is to be had. While Californian virgin quicksilver is offered at $115 
for shipment from California, the arrivals are slow and such lots as 
actually reach New York demand a good premium. The last business re- 
ported has been done at $119 spot New York.

Tin prices have actually reached 90c. per pound, quoted for spot 
Straits tin, but with the metal market closed from December 21 to 26 the 
position might undergo some change and prices can only be given 
nominally. 

Charles Hardy says: On account of a large foreign inquiry coming in 
at the same time as one of our largest users at home appeared in the 
market, the tungsten market has been exceedingly firm during the past 
week and most good-grade ore in New York found ready buyers, even 
material on steamers shortly due was readily absorbed by the market. The 
tungsten price remained steady at a sbght advance and $24.50 was paid 
for high-grade wolframite with prices ranging lower for off-grade ore. 
Such scheelite as was offered was readily sold at $26 per unit. The year 
closes with a firm market with a good demand and the prospects for the 
new year of prices continues at least on the present level if not higher. 

Again an active business has been done for such molybdenum as can be 
delivered immediately. The demand is quite good and prices range from 
$2.25 to $2.30. according to grade. 

The shipping conditions interfere largely with the regular arrivals of 
manganese ores and such small lots as reach New York market from time 
to time readily find buyers at a premium over the schedule price, which 
still remains at $1 20, delivered at furnace, for the 48% ore.

Eastern Metal Market 



New York, December 26. 

The year draws to a close with all the markets inactive and 
with two important metals under strict Government control, 
namely copper and tin, and also with the prospect that lead 
and zinc will pass under similar regulation when the condi- 
tions warrant. In 1917 copper, tin, and lead reached higher 
levels than at any time during the War, but, as the year ends, 
all the metals are lower than in many months, with the ex- 
ception of tin which now stands at the highest level in its 
history. 

Today copper is unchanged, but moving freely at regulated 
prices. 

Tin is still scarce and nominal. 

Lead is firm, but inactive. 

Zinc is a little stronger, but quiet. 

Antimony is lifeless and unchanged. 

In the steel market the year ends with practically an 
assured prospect that there will be no important changes in 
present fixed prices, at least during the first quarter. A proc- 
lamation by the President is expected daily which may extend 
the operation of the present schedule. Stocks of pig-iron have 
been so depleted for steel-making purposes that, as these are 
nearly gone, there has resulted a scramble for iron that would 
have sent prices sky-high but for Government regulation. 
The prospects are that there will have been a material increase 
in both pig-iron and steel production in 1917 over 1916, and 
the latter was a record year. 

COPPER 

There seems to be no reason for believing that there will be 
any change in the price of copper for at least three months. 
Continuance of the present prices is practically assured so 
far as steel is concerned, and it is inferred as to copper. With 
the market controlled absolutely as to price, sales, and dis- 
tribution, and with everything subservient to war-needs, there 
is no chance for excitement in the market nor for any activity 
as in normal times. There seem to be ample supplies for most 
purposes, the only impediment being delays in shipments be- 
cause of railroad congestion and storms. Sales are being 
made for first-quarter delivery of all grades of copper at 23.50c. 
per lb. in the larger market, and at 24.67*c in the jobbing 
realms. Metal is being released for commercial as well as for 
war-needs, where possible, and satisfaction seems to prevail 
generally. 

TIN 

The utmost confusion and delay in the matter of import 
licenses continues. Some importers are in serious straights, 
and are decidedly discouraged. In more than one case, be- 
cause of delays in the mails or for other reasons, licenses from 
Washington have been late in reaching New York, so that no 
further extensions in general orders were possible and the 
metal went into general stores. This has resulted, despite the 
utmost efforts to secure information even by cable as to incom- 
ing metal, and to comply with Government requirements as 
fully as possible. Tin actually has been piling up on the docks, 
for it cannot be accepted through the custom house until the 
importer obtains his license. Because of these conditions, im- 
porters are burdened also with additional expenses, and there 
are no prospects of transferring these to the buyer. The 
scarcity of all grades continues unrelieved, and the market as 
a whole is quiet and uninteresting. Sales of all grades for all 
positions have probably averaged only 50 tons per day for the 
last week. These have been mostly prompt shipment from 
England and far futures. Spot Straits is again nominal at 



S5 to S6c. per lb., New York, with none offered. Some quote 
even a higher nominal level. Arrivals to December 21, in- 
clusive, have been 1225 tons, with 4400 tons reported afloat. 
An advance of £4 10s. per ton has been recorded in the London 
market for spot Straits. The quotation on December 21 was 
£309 10s., as compared with £305 on December 19, these being 
the latest cables published. 

LEAD 

The moderate easiness referred to a week ago in the lead 
market, resulting in a slight recession in prices, with sales at 
6.40c, New York, has disappeared. The market is now firmer 
at the old level of 6.50c, New York, or 6.35c, St. Louis, for 
early delivery. This is not explained as due to a more active 
demand, but as induced by an unwillingness of sellers to part 
with metal not under contract, since they are apparently well 
booked with orders. The American Smelting & Refining Co. 
still quotes 6.25c per lb., New York. The congestion on the 
railroads is a decidedly disturbing factor in both lead and zinc 
and no relief is apparent. Early last week considerable export 
business is reported as put through, and there are negotiations 
on foot for more. 

ZINC 

The market is a little stronger than a week ago, with prime 
Western for early delivery quoted today at 7.75c, St. Louis, 
or 8c, New York, but with no sales at these levels to establish 
this price. The better tone is attributable to the announcement 
of the bids on 1000 tons of grade C zinc for the Government, 
referred to last week. These were higher than expected, and 
ranged from 7.87Jc, New York, to 8.60c, New York, with the 
New Jersey Zinc Co. as the low bidder. Grade C is only 
slightly better in quality than prime Western. On Saturday. 
December 22, bids were also taken on 4000 tons of the same 
grade for the Army, but these had not been made public at this 
writing. This disclosure is awaited with interest. In general 
the market is quiet, with few sales in any quarter reported, 
and not much inquiry. Future deliveries are quoted at J to 
3 c higher than the levels for nearby metal. 
ANTIMONY 

Chinese and Japanese grades are unchanged at 15c per 
lb., New York, duty paid, for spot or early delivery. The 
market continues dull and uninteresting. 
ALUMINUM 

The market is without interest at 36 to 38c. per lb. for No. 
1 virgin metal, 98 to 99% pure, for early delivery. 
ORES 

Tungsten: The market is regarded as a little firmer, with 
slightly higher prices paid for wolframite, the better grades 
bringing $24.50 per unit in 60% concentrates. Scheelite has 
again sold for $26 per unit. A good demand from a large 
domestic consumer, combined with large foreign inquiry, has 
contributed the better tone to the market. 

Molybdenum and antimony: At prices varying from $2.25 
to $2.30 per lb. of MoSj in 90% material active transactions are 
reported the past week. Antimony ores are nominal at $1.75 
per pound. 

Manganese ores: For domestic ores a leading Eastern dealer 
quotes as follows: $1.20 per unit for ore containing 50^- or 
more of manganese: $1.10 per unit for ore averaging 46 to 
49.99%; $1 per unit for 42 to 45.99% ore; and 90c per unit for 
38 to 41.99% ore. For all these grades maximum limits of 10% 
silica, 0.20% phosphorus, and 3% iron are stipulated. For 
Brazilian ore $1.10 to $1.20 per unit is quoted, and as high as 
$1.30 per unit has been paid for Indian ore.

CALCULATING MACHINES FOR ENGINEERS 



By R. M. FARMER 

For many years adding or calculating machines have been 
used in the offices of mining or smelting companies tor or- 
dinary routine work. It has long been recognized that they 
offer tar more dependable accuracy and speed than the fastest 
human calculator could give, but, until recently, these ma- 
chines did not find favor among men responsible for the 
technical details of operation for the reason that they were not 
sufficiently flexible in scope to include all the intricate calcula- 
tions which occur in the work of mining and metallurgical 
engineers. Technical men were on the alert for a machine 
that would meet their requirements, for they realized that 
mechanical accuracy and speed are to be preferred to the 
fastest calculator, with his human tendency for error, or to 
the most adept user of a slide-rule. When such a machine was 
finally perfected it met with almost instant approval, and has 
since shown remarkable saving in time and in the intangible 
but very real losses occasioned through some slight error made 
when the brain was tired or when a guess between the gradua- 
tions of a slide-rule was a thirty-second of an inch out of the 
way. 

The appliance which has thus met the demands of technical 
men is the 'Monroe calculating-adding machine.' First used 
as an experiment, it has now become part of the standard 
equipment of the engineers and operators of such concerns as 
the Utah Copper, Braden, Chino, Ray Con., Phelps-Dodge, 
American Smelting & Refining, St. Johns, Cerro de Pasco, and 
many others. 



The uses for the Monroe machine are legion, as the machine 
adds, subtracts, multiplies, and divides, with positive action 
and without the disadvantage common to other similar devices 
and to the slide-rule of having to carry some governing factor 
in the operator's mind, such as proper placing of the decimal- 
point or the number of times a multiplier or divisor has been 
used.

figures, or in estimating ore-reserves at 
a mine, an appreciable amount of time is 
saved with a Monroe calculator, to say 
nothing of the assurance that the ac- 
curacy is positive. The following ex- 
ample illustrates this fact. 

Problem: to determine the number of 
ounces per ton in a vein of ore: 

Width, ft. Assay, oz. Foot-ounces 

7 1.22 8.54 

4 0.54 2.16 

12 1.20 14.40 

8 2.20 17.60

6 0.39 2.34 

6 trace .... 

7.2 trace 

66 204.78 

204.78 

= 3.1 oz. per ton

This was computed on the Monroe in 
37 seconds.

The time taken on the Monroe calculator was 17 seconds. 

It has been shown that the operating speed of a Monroe 
calculating machine is greatly less than that obtained by other 
methods, but that the chance for inaccuracy has been brought 
to an irreducible minimum as well. When a problem is 
worked, the answer appears at the top of the machine, while 
at its side is shown a mechanical check on this answer. In 
multiplication, for instance, the multiplicand remains on the 
key-board, the answer appears on the lower dial, while on the 
upper dial is shown the multiplier (Fig. 2). Thus, no doubt 
is left in the operator's mind as to the accuracy of his cal- 
culation. 

Simplicity of operation is a feature of the Monroe. To add 
or to multiply, the crank is turned in one direction, to subtract 
or to divide, it is turned in the opposite direction. Anyone 
who can push a button and turn a crank can use the Monroe. 
It has been found that the average man, unfamiliar with the 
machine, can attain fair speed in one week. At the present 
time, the Monroe is being used in the work of mining and 
metallurgy for estimating ore-reserves, surveying problems, 
calculation of assay and laboratory results, office routine, struc- 
tural engineering problems, and cost-accounting in the office 
and in the operating plant. It should be borne in mind that 
the calculating machine finds its greatest usefulness on in- 
volved problems, and in rushing through work in a limited 
amount of time. As one mining engineer remarked, "we had 
to do two weeks work in three days and the Monroe seemed 
to be the only way out." When you have calculations as long 
as your arm, and as intricate as a mine-model, it is well to 
bring mechanical accuracy to your assistance. When one has 
been working night after night to late hours, the brain is cer- 
tain to tire. Then it is that the human tendency for error is 
most liable to crop out, but even in such times of rush and 
worry, the Deus ex machina is infallible. It is well to let him 
shoulder the petty details of figuring and checking, and to save 
your brain for constructive thinking. 

The calculating-adding machine used by all of the afore- 
mentioned mining and smelting companies is made by the 
Monroe Calculating Machine Co., Woolworth building, New 
York. Any request for detailed information should be ad- 
dressed directly to them.

mechanism is used in this drill. It possesses an exceptionally 
quick movement, and enables the hammer to strike fast and 
hard blows. This valve cuts off early, which allows the air 
to expand in the cylinder, thus saving power. Both valve and

DRY PLACER 
MINING 

In the desert country of Arizona where 
no water Is available, the Sauerman drag- 
line cableway excavator is making a record 
in the economic handling of dry placer 
material. 

In all classes of dry excavating, as well 
as under water, the Sauerman cableways 
are handling material cheaper than is pos- 
sible with any other form of excavator for 
this class of work. 

For Placer Mining, either wet or dry, 
Sauerman excavators afford the ideal 
means for dredging and handling gravel 
and dirt. 

FOR HANDLING LARGE TONNAGE 

It is not economical with many placer properties to equip with expensive dredges for handling 
material. 

Sauerman excavators afford the means of handling materials at an installation cost that is insignifi- 
cant as compared with that of the gold, platinum and tin dredges. 

Let us send you a description of a dry placer property's equipment which affords one of the most 
difficult types of placer operations where a Sauerman excavator is in successful operation.

Milling Efficiency 

The ratio of extraction and operating cost to tonnage 
treated is what you are primarily interested In. 

THE KOERING PROCESS of Cyanidation as has been 
demonstrated, will increase the efficiency of your mill by 
at least 35 per cent. THE REASONS ARE: 

1. Treating sand and slime together. 

2. Thorough agitation and aeration of pulp. 

3. Filtration without filter presses. 

4. Ability to wash all dissolved values from the pulp. 

5. Reduces cyanide loss to a minimum. 

6. Avoids settling agents. 

7. Treating ores formerly unadaptable to cyanide. 

8. Increases your extraction from 5 to 15%. 

9. Ability to complete entire cycle of treatment in a 
few hours. 

10. A reduction in labor charge of 75%. 

11. A filter which avoids clogging and needs no chang- 
ing for years at a time. 

12. The amount of mill solutions Is insignificant as com- 
pared with the older processes. 

13. The equipment for agitation, filtration and washing 
is in one unit. 

14. Simplicity in construction and operation. 

THESE CLAIMS ARE SUBSTANTIATED by results ob- 
tained in actual milling operations.

Straub Stamp Mill 

AWARDED 

GOLD MEDAL 




PANAMA -PACIFIC 
INTERNATIONAL 
EXPOSITION 



Our mills are made in three sizes 
— 8-ton, 12-ton. and 20-ton — and 
are metalled in all sections of 
the country, from Alaska to Cen- 
tral America. We claim a larger 
s range of crushing than any other 
mil] both in hardness of ore and 
size of screened product. 

One man writes from a remote 
part of Central America, "I have 
operated the Straub Mill on every 
grade of ore from the very hard- 
est quartz to clay, and find it all 
that any man could expect." He 
has one of our 8-ton mills, and 
says, "I am getting upwards of 
18 tons on oxidized ore." 

THE STRAUB STAMP pays for 
itself in the saving it makes over 
ordinary mills on transportation, 
erection, and operating costs. Two 
men can erect a STRAUB mill 
ready for operation in two days.

with 

Fewer Men 

It relieves the strain at the point of unloading the mine cars, 
by affording unlimited speed and quantity in dumping. 

It relieves the acute labor difficulty by cutting down the 
number o£ men required, thus not only saving in labor 
costs of dumping, but releasing men for use elsewhere.

THE EXAMINATION OF PROSPECTS 

By C. GODFREY GUXTHER. E.M. 
Author of "Electro-Magnetic Ore Separation." 



222 Page*, 79 Illustration*. Leather. Pocket Size. 
92.00 Postpaid. 



Mr. Gunther's book emphasizes not only the fundamental 
business aspects of prospecting', but also the applications 
of economic geology to the examination of prospects. 

The first part of the book covers the general considera- 
tions — the preliminary phases of the "work. The latter deals 
with deposits — types, distribution, structural features, ores 
and ore-shoots, etc. 

It is a compact practical book.

BRAUN 

K. & K. FEEDER 

FOR OILS AND ACIDS 




A Small Machine Which Fills a 
BIG NEED IN SUCCESSFUL FLOTATION 

In feeding oils and other reagents it is neces- 
sary that exact quantities be fed continuously, 
and as these quantities are small, much trouble 
has been experienced in devising means to ac- 
complish the results. When attempting to feed 
oil through small pet cocks it has been found 
that grit, sludge and other foreign matter would 
clog up the opening and cause annoyance and 
inaccurate results. The BRAUN K. & K. Feeder 
is the most practical device, and absolutely 
eliminates detrimental metallurgical results due 
to irregularity in the feed. 

The machine is made in two types — one for 
Oil and one for Acid. The Acid Feeder is con- 
structed of lead and bronze to withstand re- 
agents. 

Measurements: Length, 23 in.; width, 16 in.; 
height, 15 in. 

Braun K. & K. Oil Feeder, $40.00 
Braun K. & K. Acid Feeder, $75.00

has enough play to allow 
suitable seating when the 
plug is turned down to the 
seat of the valve. There 
are many of these valves 
in use giving excellent 
service. 



Those who are having trouble through the 
necessity for frequent replacement of fit- 
tings, valves, or the metal parts in contact 
with acid solutions will do well to write us. 
We can help you.

Halves Mine Haulage 
and No Exhaust Fumes — 

The Plymouth Friction -Drive Gasoline Locomotive is cheaper to 
buy than any other gasoline locomotive, steam dinkey, electric 
motor, compressed air motor, or mules, and Is cheaper to operate 
and maintain. 

There are no gas fumes from exhaust to endanger lives: it hauls a 
greater load than any locomotive of same size and performs feats 
with its friction-drive no gear-driven locomotive can do.

CutsHaulag'efostsOneHaU 



These two mines quoted below have used The Plymouth Friction- 
Drive Gasoline Locomotive for more than two years and verify each 
statement made above: 



"It costs half of our old system 
to operate," says Southern Con- 
nellsville Coke Co., Uniontown, 
Pa., "and we have no trouble 
from fumes caused by gasoline 
exhaust."

"Our Plymouth goes 2100 feet 
into the shaft." says American 
Gypsum Co., Akron, N. Y„ "but 
at no time are we bothered 
with gas fumes. Costs half to 
run." 
It tells the complete story of the two in- 
stallations mentioned above and 33 others, 

giving comparative fuel, labor and repair costs, wave line charts. 

etc. A copy free to anyone.

Eliminate 
power losses! 

The present strain on industry makes imperative the 
production of power with a minimum consumption of 
fuel. High boiler efficiency is a necessity. 

A tight blow-off while only one of the contributing 
factors to efficient operation, is of vital importance — 
a small leak at this point having a marked effect in 
increasing power costs. 

The 

LUNKENHEIMER 

"Duro" 

Blow-off Valve. 

is the logical valve for this important service. It 
will remain tight under the most severe operating 
conditions. 

The peculiar construction of the "Duro" Seat-ring 
and Disc provides self-cleansing, seating surfaces. To 
further enhance its durability, the Disc is reversible, 
and all parts including the Seat-ring and reversible Disc 
are renewable. 

The ideal blow-off combination is the "Duro- Victor". 
The "Duro" is used for the blow-off, with the "Victor" 
in reserve for emergency. 

There is a size for every boiler; with material com- 
binations to suit all pressures and service conditions. 

Specify Lunkenheimer "Duro" and insist on its in- 
stallation. 

Tour local dealer can furnish them ; if not, write us. 
Write for Booklet No. 515-CD.

When Loads are Heavy 

One of the most important qualities of a Wire Rope is 
DEPENDABILITY, for when your Rope breaks your 
work stops. The success of Hercules ( Red Strand ) Wire 
Rope is largely due to the fact that it can always be 
depended upon. It has the nec- 
essary strength to handle heavy 
loads and its extreme toughness 
and flexibility make it remark- 
ably durable.

Quick Action! 



This little mill is pointed to as the most modern and most efficient 
in the Boulder County tungsten field. 






We designed, equipped and erected it 

complete, and turned ii over in il wners 

HI days after the signing of the contract. 
It started immediate production without a 
hitch of any kind and returned its entire 
cost to its owners in the first four weeks' 
operation. 

Only a perfect combination of sound 
metallurgical knowledge, ample manufactur- 
ing facilities, a proficient erecting organiza- 
tion and extensive mill building experience 
made this possible. 

If you are planning the erection of a mill, money 
will be saved by contracting for its design and 
erection complete. But. the contractor should be 
experienced and responsible, should have such 
ample facilities that he is practically independent 
of others, and should have such a reputation as 
promises the faithful performance of his engage- 
ments.

44 T T is a trite thing to say that we are not awake. We 
■*■ are awake. We know there is a war, but the thing 
is so big we do not comprehend it. We are asleep so far 
as recognizing the iull significance of the figures is con- 
cerned — of understanding how gigantic the task is. ' ' So 
says Mr. Vanderlip. Every man that loves his country 
should daily put the question to himself whether he has 
grasped the magnitude of what is yet to be done to make 
the world safe and serene with the assurance of freedom 
to live worthily and in peace. He should ask himself 
whether he has done all that he might do to aid in rid- 
ding the world of crushing imperialism. The conscience 
and purpose of a democracy are the expression of the 
sentiments and purposeful activities that predominate 
among the individuals composing it. Let every man- 
write the query "Have I done my best?" and put it 
where he must see and answer it each day. 



RECOGNITION of the importance of training young 
men as technologists has been made by the War 
Department. Apparently the new regulation is well 
conceived to protect the country against depletion of its 
force of engineers and chemists. All technical students 
are accorded the privilege of enlisting in the engineers' 
corps, and after enlistment they may present a certifi- 
cate of standing in their studies properly attested by 
the officials of the college or training school, accom- 
panied by a petition for leave of absence until gradua- 
tion. This permission is conceded automatically under 
the ruling of the War Department when the certificate 
presented shows that the academic grade of the appli- 
cant is as high as the upper third of the average grade 
of all students in the same school for the past ten years. 
This order disposes of one vitally important question in 
a manner that must win the commendation of all citizens 
that have thought seriously upon the larger problems of 
our national need. 

SILVER has risen above 90 cents. The quotation ap- 
pears to be responding to the intimation that the 
governments of the United States and Great Britain 
have arranged to purchase 100,000,000 ounces of the cur- 
rent year's production with a view to stabilizing the 
price of the metal; but we are informed that the Gov- 
ernment, without specifying any definite quantity, is to 



authorize the Director of the Mint to buy all the silver 
that is offered. It is rumored that the price is to be 
fixed somewhere between 94 and 97 cents. China is an 
active buyer just now, shipments from San Francisco 
westward having been at the rate of five to six million 
ounces per month. Not more than one month's produc- 
tion — 8,000,000 ounces — was available for the coinage 
needs of our own government and that of England, so 
that the rise to $1.15 in September was not surprising 
and it might have continued even to $1.25 if an artificial 
cheek had not been established. The miners of silver 
protested against this interference with their oppor- 
tunity to obtain compensation for the low prices pre- 
viously prevailing and expressed a keen desire that 
official hands might be kept off the market. We under- 
stand this point of view, but believe it to be short-sighted. 
The fixation of the price at a moderately high figure, 
double the lowest quotation of three years ago, is better 
for the mining industry than a hysterical market afford- 
ing no assurance of steady profit. As we announced in 
a recent issue, credible gossip in financial circles arouses 
expectations of an international agreement for a bi- 
metallic monetary basis. Thus, and thus only, could the 
two metals be associated so as to bolster the credit 
requisite for the expanded volume of international 
finance. There was no doubt that France was favorably 
disposed toward bi-metallism, if Great Britain would 
follow suit. The indications now point toward an un- 
derstanding on this subject among all the allied nations. 

COPPER mining at the Calumet & Hecla is the sub- 
ject of a short article appearing in this issue from 
the pen of an experienced journalist, Mr. Homer Guck. 
He tells the story of the great copper mine that has 
given fame to the Lake Superior mining region and in- 
cidentally refers to the accident of discovery, through the 
unearthing of a 'cache' or store of copper by an enter- 
prising pig. Edwin J. Hulbert is given as authority 
for this tale. It does not conflict with the account given 
to the present writer by James D. Hague. In 1853, 
while surveying for a road, Hulbert had found detached 
pieces of copper-bearing conglomerate and in 1858 he 
discovered the so-called ancient pit, which may be the 
same as the hole in which the boarding-house pig pros- 
pected with his snout. Such evidences of the existence 



40 



MINING and Scientific PRESS 



January 12, 1918 



of a copper lode did not lead at once to the discovery of 
ore in place, for this did not follow until August 1864, 
when Hulbert sank a prospect-hole on a tract of mineral 
land that he had selected for exploration, and struck the 
Calumet conglomerate. Fortunately the ore was so rich 
at the point of discovery as to encourage development. 
However, the first ore produced for market from the 
Calumet lode was mined at the bottom of the 'ancient' 
pit early in 1866. It yielded 12% of copper. Thus, 
while the pit contained a 'cache' of copper, mined else- 
where, it happened to have been dug at a spot immedi- 
ately above the copper-bearing conglomerate, but not so 
deep as to expose ore in place. This recalls the story 
of Chicken Bill and the Chrysolite, at Leadville. Our 
readers will remember that H. A. W. Tabor bought a 
claim, called the Chrysolite, from a notorious prospector 
called Chicken Bill. This enterprising person had not 
waited for his shaft to reach the ore-bearing limestone, 
but had taken rich ore from the Little Pittsburg mine 
and had 'salted' the bottom of the shaft. Tabor was de- 
ceived and paid $40,000 to Chicken Bill, who then began 
to brag about his trick to some of his friends, so that the 
news of it reached Tabor's clients before he himself 
reached Denver, whereupon they repudiated the deal 
and Tabor had to keep the claim. He sank the shaft 
deeper and struck wonderful ore — this time in place ! 
The Chrysolite yielded $1,500,000 in profit to Tabor and 
his associates before they sold it to a New York company 
for another $1,500,000. 

Mexican Conditions 

Mexico is said to be emerging from political chaos, but 
her economic condition is deplorable. A recent traveler, 
competent to judge through long familiarity with the 
Spanish language and the ways of the country, informs 
us that no real progress in reconstruction is being made. 
The Mexicans assumed that they could apply the magic 
touch of a socialistic constitution and, presto! the re- 
sources of the mine and farm would leap into the mints 
and granaries. The little matters of capital and indus- 
try and discipline were quite overlooked. It was to be 
expected that the socialists would disdain the need of 
capital, since they blame most of the disappointments of 
man upon the capitalistic system, without in the least 
comprehending the true meaning of capital nor realizing 
the wrong construction that persistently has been put 
upon the teachings of Karl Marx by his avowed dis- 
ciples. At all events the Mexican free-for-all non- 
capitalistic handicap is proving a dead failure, and the 
people are cooling down to a point where the govern- 
mental leaders can explain to them the need of help, even 
from the 'gringo.' Our correspondent remarks that the 
Mexicans are beginning to see that, "in asking for help 
it must be on the understanding that the management, 
and the control of funds and revenue, will be demanded 
and required." 'Mexico for the Mexicans' is an excel- 
lent slogan, but it has nothing whatever to do with the 



peaceful and normal development of their natural re- 
sources by outside capital. If the Mexicans will set aside 
their impossible constitution of Queretaro, swing back 
to the bill of rights in the constitution given them in 
1857 by their true patriot, Benito Juarez, eliminate the 
principles of monopolistic concessions, thereby at one 
stroke cutting off the main artery of graft that has 
brought them so much evil government, they may hope 
to see their country arise from her desolation. It is not 
the wish of the people of America that Mexico should 
be humiliated, nor that it should be over-run by our 
army and annexed. The fact that we were able, when 
sufficiently stirred by a genuine national peril, to put 
on the trappings of war and display a strength before 
which any small nation might well stand abashed, is 
proof enough of the national attitude of mind. We do 
not even hint at an invasion of Mexico, although we 
are now in warlike temper. Mexico knows that she is 
safe against attack from her big neighbor of the North, 
despite the inconsiderate statements that sometimes 
creep into the daily press. We regret, for example, 
the intemperance of certain reporters who recently have 
made 'copy' out of ridiculous imputations to Governor 
Cantu of Lower California of a wish to offer his 'princi- 
pality' to this country. Such nonsense, written by boys 
who are more smart than learned, and who know nothing 
of the history of Mexico and of the special fervor of her 
patriotic sentiment, utterly misrepresents both coun- 
tries. Governor Cantu is a man of unusual intellectual 
gifts, a thoroughly progressive man, and so well dis- 
posed toward America that he is offering to supply us 
certain raw materials that we need; but he is also a 
Mexican, and the last thing a Mexican would do is to 
relinquish so much as a rock or a sand-spit of the Patria 
to a foreign power, save under compulsion of arms. 
Whatever family quarrels Governor Cantu may have 
with his political associates he is no traitor to his coun- 
try, and the American people would despise him if he 
were. Mexico needs our kindly assistance at this mo- 
ment, and we believe that she will look to us for the 
sort we can best render as soon as Argentina shall have 
cast to the winds the fiery anti-American doctrines of 
Manuel Ugarte and have aligned herself with the powers 
contending against Kaiserdom. Mexico needs, not only 
capital, but a close association with our banking system 
to re-introduce the machinery of credits, without which 
industrial recuperation is impossible. Just now the 
authorities have adopted make-shift means for obtaining 
a considerable amount of American gold coin through 
their customs and tax departments, and are endeavoring 
to re-coin it as fast as it can be delivered to the mint in 
Mexico City. This resource, however, is relatively small, 
since the exportation of gold from this country is per- 
missible now only upon special executive order, and that 
is not conceded unless the circumstances render it pe- 
culiarly necessary. Practically, Mexico is dependent 
upon the gold produced from her own mines, and upon 
a return of 25% of exported silver in a gold equivalent,

and that equivalent amount constitutes the larger part 
of what is obtainable under export licenses, to which is 
added the quantity required to saw American invest 
ments on which payment of taxes in gold is obligatory, 

which amounts to a little over $10,000,000 per month. 
If not paid, and in gold, the property is, hy decree of 
Carranza, subject to forfeiture to his Government. In 
order to stabilize Mexican currency the fiat paper has 
been retired, but the basis for bank-credits in proper pro- 
portion for a large expansion of industry is lacking. The 
banks are endeavoring to liquidate their outstanding 
circulation as rapidly as they can, and some are buying 
up their bills at a given rate in the open market, while 
others remain dormant, anticipating better conditions. 
We are finding that conscription of capital is impossible, 
and Mexico has found that its twin sister, confiscation 
of capital, is impossible. Such drastic actions result in 
extinction of the country's resourcefulness. It is in the 
encouragement of industry, and in the creation of con- 
fidence whereby the resources may multiply their use- 
fulness as bases for credit, that the real ends of national 
development are subserved. The interests of Mexico and 
the United States are inter-related because of propin- 
quity and because of the complementary nature of the 
resources of each country. For purposes of finance no 
wide division can be drawn between them without 
mutual harm. As friends and allies we can be of assist- 
ance to each other, and our financial support will ensure 
the growth of a free and prosperous Mexico. The ques- 
tions of reform have nothing to do with the gringo ; these 
depend on the wisdom of the Mexicans themselves. 



Geology at Jerome 

Truth is stranger than fiction and facts are more ro- 
mantic than fables. In this issue we conclude the story of 
the U. V. X. bonanza, telling how the wonderful orebody 
of the United Verde Extension mine, at Jerome, Arizona, 
was found by Mr. James S. Douglas. The thoughtful 
reader will not have overlooked the strange coincidence 
whereby James Douglas, the elder, missed getting hold of 
the United Verde, which William A. Clark acquired, to 
his great enrichment, and how Mr. Clark missed the 
riches in the United Verde Extension, so that it was left 
for James Douglas, the younger, to unlock that treasure- 
vault. ' ' The whirligig of time brings in his revenges. ' ' 
We may remark, however, that both Dr. James Douglas 
and Senator Clark, as they are now known, were so suc- 
cessful in their mining operations elsewhere that the 
rejection of the United Verde by one of them and the 
missing of the United Verde Extension by the other have 
not proved disappointments of a tragic kind. Still we 
rejoice that the final achievement was left to the younger 
man and to his friends, so that the wealth of Arizona 
has found wider distribution. If there must be a moral 
to the story it is that the miner should not disdain the 
aid of the geologist. Senator Clark in vulgar phrase 
'had no use for' geologists. That is accountable in part 



by his unpleasant experie with Mr, George w. Tower, 

of the O. S, Geological Survey, at Butte; tor thai geolo- 
gist had access to the Clark mines in his official Capacity, 

and when I"' resig I from the Survey he used his in 

formation as an expert witness in t he local mining liti- 
gation, which at one time had many of the character- 
istics of a vendetta. That may excuse the Senator's 
strong prejudice dining recent years, but not his earlier 
inhospitality to geologists, whether official or unofficial. 
The lute S. P. Emmons, a man to whom the Tower epi- 
sode, made known in 1903, seemed a blow at the honor 
of the Survey, being himself most scrupulous in his use 
of information obtained as an officer of the Survey, 
records regretfully the fact that Mr. Clark's policy of 
excluding visitors, especially geologists, from the United 
Verde, prevented him from studying the evidence of 
secondary enrichment existing in that mine. That was 
in 1899. It is significant that when H. H. Rogers was 
organizing the Amalgamated Copper combination in 
1898 he proposed to include the United Verde, but the 
negotiations broke down when Senator Clark refused to 
allow an examination to be made. So geologists were 
persistently excluded from the United Verde, and the 
Senator was so prejudiced against them that he did not 
employ one to guide him or his manager in the develop- 
ment of the mine. The consequence was that the com- 
bined effects of geologic faulting and secondary enrich- 
ment were not correctly apprehended, and it remained 
for a mining engineer from the outside to come into 
Jerome and uncover the bonanza under the noses of the 
people that had been exploiting the United Verde for 
25 years. We do not insist that all the geologists made 
correct inferences; the story of the U. V. X. discloses 
the fact that several of them — and some pretty good men 
too — guessed wrong; but that is to be expected, seeing 
how young the science of ore deposits is and how un- 
certain are many of the criteria on which it is based. 
Still the U. V. X. remains a triumph of sound observa- 
tion and scientific reasoning; it is far removed from the 
lucky accidents that started most of the great mines of 
the West, from the Comstoek to the Camp Bird. The 
enterprise organized by Messrs. Douglas and Tener is 
also noteworthy as a clean promotion and a straight- 
forward piece of business. It was conducted on a high 
level of integrity from start to finish; affording a good 
example to other incubators of mining adventure. It 
is not the fault of Messrs. Douglas and Tener if the 
U. V. X. has been used as an excuse for breeding a 
vociferous litter of wild-cats. The promoter of a puling 
prospect can point — and has not hesitated to do so — at 
the U. V. X. as a rich mine that was started on nothing, 
a successful development predicated on no surficial 
showing of ore ; and, as one might expect, the so-called 
fiscal agents and other organizers of hair-brained schemes 
for collecting money from the public have used the 
U. V. X. story as an argument that can only be answered 
by those aware of the facts. The publication of the real 
story should serve to check a distortion of the truth, 
while at the same time offering encouragement to intel-

ligent exploration. The idea that there are 'one mine' 
districts — that a single mine may include within its 
boundaries all the rich ore in a given locality — is a notion 
that should be thrown aside. If it were given to the 
miner for an instant to have a radioactive vision enab- 
ling him to see into the crust of the earth, he would, we 
think, be astounded to see how much ore he had missed, 
even close to the workings he had made. Probably the 
undiscovered ore greatly exceeds that which has been 
mined, could we but see it, which is equivalent to saying, 
could we but find it without spending an excessive 
amount of money in the search. The geology of the 
Jerome district is yet to be deciphered. For that the 
microscope of the petrographer is necessary. Several 
experienced geologists have examined the district re- 
cently, and even the United Verde can now boast a com- 
petent guide in these matters, so we shall hope that fresh 
evidence will be produced, to the end that a clear and 
comprehensive explanation of the rock-structure may be- 
come available. The energetic prospectors along the line 
of the big fault need such help, and they ought to have 
it. Undoubtedly they would have had it long ago if the 
United Verde had not been closed to the U. S. Geological 
Survey; and now that the U. V. X. is open to official 
inspection the Director of the Survey should lose no time 
in delegating members of his staff to make an examina- 
tion. Timeliness is essential to a geological report. Deli- 
cately worded obituaries and meticulous post-mortems 
are not in demand by those engaged in the operation of 
mines. It may be that Mr. Douglas's venture will fur- 
nish scientific evidence of great value, as well as much 
copper for making the munitions to be used in the 
achievement of victory on the battlefield. He undoubt- 
edly is glad to have his copper put to military use, for 
he is a large-scale American whose heart is in the Great 
Cause — and more than his heart, for his son is in the 
U. S. Army, and he himself, leaving the accumulation 
of millions, is in France, serving the Red Cross with a 
bigness of spirit that is more than all the wealth of a 
copper mine, even of the one with which his name will 
remain forever linked in honorable fame. 

ExcesS'Profit Tax 



Referring to the incidence of this tax on mining, we 
have expressed doubt concerning the practicability and 
fairness of the Act passed by Congress on October 3. 
It is a pleasure, therefore, to record the fact that a com- 
mittee representing the mining, oil, and gas industries 
was organized early in December under the auspices of 
the American Mining Congress to discuss the matter 
with the Advisory Board of the Bureau of Internal 
Revenue. The committee consisted hi the following rep- 
resentative men: J. J. Shea (Oklahoma), A. G. Dickson 
(Pennsylvania), Herbet Pope (Illinois), Ravenel Mac- 
beth (Idaho), A. G. Mackenzie (Utah), Emmet F. 
Boyle (Nevada), T. A. Dines (Colorado), A. Scott 
Thompson (Oklahoma), Victor Rakowsky (Missouri), 



Paul Armitage (New York), Archibald Douglas (Ari- 
zona), and Albert Bureh (California). After a confer- 
ence with the Advisory Board, the committee was asked 
to formulate such an amendment to the present law as 
would be satisfactory to those engaged in mining. We 
do not repeat the reference to "oil and gas," because 
the exploitation of oil and gas deposits is 'mining,' and 
the distinction attempted to be made is a technical 
blunder. The amendment of Section 207, of Title 2, of 
the Act, was as follows: "That in the case of mines, oil 
and gas wells, the invested capital, at the option of the 
tax-payer, shall be (1) the average pre-war net income 
capitalized at 8%, and (2) paid in or earned surplus and 
undivided profits used or employed in the business since 
the pre-war period, exclusive of undivided profits earned 
during the taxable year; provided, that in the ease of 
mines, oil and gas wells, having no pre-war net income, 
or acquired since the pre-war period, the 'invested capi- 
tal,' at the option of the tax-payer, shall be (1) the net 
income for the year 1917 capitalized at 12%, and (2) 
paid in or earned surplus and undivided profits used or 
employed in the business subsequent to the year 1917, 
exclusive of undivided profits earned during the taxable 
year." This is not an amendment that can be approved, 
for it attempts to define while using terms that them- 
selves need definition; moreover it will bear inequitably 
upon individual mines and is unlikely to meet the re- 
quirements of the Government. A later suggestion, 
made by Mr. Albert Burch, who was unable to be present 
at the conference, reads thus : "In the case of mines, oil 
and gas wells, the increase in the average price received 
at place of sale for each unit of product, that is, each 
ounce, pound, ton, barrel, or cubic foot, as the case may 
be, for the taxable year over the average price at which 
the same unit was or could have been sold at the same 
place during the pre-war period shall be ascertained, and 
50% of such increase multiplied by the number of units 
produced and sold during the taxable year shall be 
deemed W ar Excess Profits and upon such War Excess 
Profits there shall be paid a tax in lieu of all other taxes 
imposed under this title at a graduated rate from 20 to 
60%, varying with the percentage of increase in unit- 
value of product." Thus the factor of 'capital' is elimi- 
nated from the problem and those that have benefited 
most from the increment of prices due to the War are 
mulcted most heavily. The 50% of profit that is untaxed 
is supposed to be absorbed by the increased cost of pro- 
duction. There should be no difficulty in applying this 
definition, which, once and for all, escapes from the 
verbal morass in which the tax-gatherer and the tax- 
payer are floundering. Misconception as to the signifi- 
cance of capital invested in mining has led persistently 
to false reasoning in tax apportionment. Invested capital 
is fixed like the mine in which it is invested. It is the 
working capital that gives it the vigor to become pro- 
ductive. Working capital, however, is subject to wide 
variation, and is not a basis for equitable taxation, but 
it is logical to demand contributions from income, because 
that is the true measure of utility.

How to Ship Ore 

The Editor : 

Sir — There appears to be a dearth of knowledge at the 
mines concerning the condition of shipments of ore and 
mill-products and the kind of containers best suited to 
the needs of the sampler and consequently to the general 
satisfaction of both shipper and smelter. A good many 
shippers appear to think that the condition of the ore or 
concentrate or precipitate, as the case may be, is im- 
material, so long as the stuff is loaded on the cars and 
sent on its way. I venture to make some suggestions 
that may appear superfluous to the initiated, but which 
to a surprising extent might be followed with resulting 
satisfaction to both shipper and smelter. 

Starting with crude ore, the first requisite is uni- 
formity of size, and the finer the better. Recently I 
noticed a shipment of silver ore from a Nevada prospect, 
the owner of which had installed a small crusher at the 
shaft; the ore was crushed to a maximum of one inch, 
sacked in good strong sacks, which were plainly marked, 
and loaded in four lots in a car, each sack bearing its lot- 
number. There was a feeling of satisfaction among the 
men' in charge when this shipment was unloaded and 
sampled at the smelter. 

About the same time another shipment was received 
from one of the oldest shippers on the Coast, supposed 
to contain three lots in a car. Some of the sacks had no 
mark on them, and nearly all were so rotten that it was 
impossible to carry them from the ear. Of course, the 
best the man in charge could do was to make an ap- 
proximate segregation of the lots after corresponding 
with the shipper. In this case two 12-in. boards would 
have made a perfect division of the three lots, and the 
sacks could have been dispensed with entirely. 

In regard to marking sacks, where there are several 
lots in a shipment. One of the best methods is to tear up 
an old pair of overalls and tie a strip of the cloth to each 
sack. Another lot could be marked with pieces from an 
old red flannel shirt, and a third lot might be left with 
no marks. I have just seen the sampling of a shipment 
of concentrate that illustrates this point very nicely. 

One of the large mining companies operating in Mexico 
shipped 578 sacks of concentrate on July 16, 856 sacks on 
July 23, and 670 sacks on August 6, each lot represent- 
ing the output of the mill for a given period. Of course, 
these lots should have been kept separate in order that 
the mill superintendent could check the returns against 
his assays, but the steamer loading the lots at the Mexican 



sea-port got them hopelessly mixed. On arriving at the 
smelter the only segregation that could be made was to 
take the number of sacks called for in each lot, as there 
were no distinctive marks. The first lot sampled was 
over a ton and a half short in weight and lacked some 
1200 oz. silver in content, which fact elicited a prompt 
inquiry from the mining company. However, on check- 
ing the total weights of the three lots, there was nearly 
one and a half tons over the advised weights, and I have 
no doubt that the total value of the three lots will be 
satisfactory. Companies making regular shipments of 
concentrate from a distance, as in this case, should use 
linen tags on which the lot-number could be stamped. 

Concentrate should be shipped in double sacks, or, in 
case of local shipment, preferably loose in the car, pro- 
vided the ear has a good floor. The car should be swept 
clean before loading and boards should be placed before 
the doors to prevent leakage. 

Shipments of flotation concentrate are becoming in- 
creasingly important, and in this connection I want to 
point out a fact that merits consideration at the mine. 
I have noticed that some millmen, in their zeal to lower 
the freight-charges as much as possible, have dried the 
concentrate, apparently at a good deal of trouble and 
expense, to as low as 1% moisture. Believe me, that is 
dry. I saw such a lot of very high-grade flotation con- 
centrate unloaded at one of the smelters recently. The 
stuff was loose in a box-car, and the wind was blowing, 
so in spite of all precautions in unloading, I believe there 
was a loss sufficient to pay a considerable part of the 
freight-bill. Then the lot had to be wetted before sam- 
pling, and as the metallic particles are coated with oil, 
it was almost impossible to accomplish the wetting, the 
result being a rather messy business all around. On the 
other hand, the moisture content should not be over 12%, 
but this is easily attained with the vacuum-filters in gen- 
eral use. I should say from my experience that the most 
satisfactory condition as to moisture for shipping and 
sampling is about 5 or 6%. 

Regarding cyanide precipitate, the same suggestions 
as to moisture will apply, only with added emphasis. 
This product should not be dried completely nor should 
it be shipped wet. I have noticed recently several lots 
containing over 40% moisture. These lots must be dried 
carefully and screened before sampling. It is hard for 
the shipper to realize that his precipitate, worth prob- 
ably $40 per pound, has lost 40% in weight before being 
sampled. 

I believe the best container for precipitate is the five- 



44 



MINING and Scientific PRESS 



January 12, 1918 



gallon oil-can, with the carbide-can a close second. These 
are convenient and safe. Usually the handiest receptacle 
around a cyanide plant is the empty cyanide-can, but 
these cans filled with precipitate will weigh up to 350 
lb., which is entirely too much weight for the cans or the 
eases enclosing them. In shipping this class of material 
it is advisable to mark the cases plainly, giving gross, 
tare, and net weights, so that the sampler or the shipper's 
representative may check the weights and notice any 
discrepancy at once. 

Almost every mine in the country enjoys an individ- 
uality in regard to the shape and size of its bars, but as 
I have noticed an apparent desire on the part of the 
smelters to standardize to some extent the size of the 
silver bullion bars, I will give the approximate dimen- 
sions of the bar that appears to be the most satisfactory 
for the individual melting and sampling, as practised 
at custom smelters. A bar 4$ by 16| in. long on the 
bottom, and 4f in. high will weigh about 2000 oz. This 
applies to the class of bullion produced at the silver 
mines of Nevada, Arizona, and Mexico. Bach bar should 
be stamped with the mine number and weight. If there 
is matte on the bars it should be removed and shipped 
separately when enough has accumulated. The matte is 
easily ground and sampled as one lot of ore.

Mineral on Agricultural Land 

The Editor : 

Sir — Your editorial comment, in the issue of December 
1, upon Leonard G. Blakemore's letter concerning 'Pros- 
pecting Conditions in California' is timely and interest- 
ing. I quite agree that retroactive regulations are con- 
trary to our fundamental law, but, on the other hand, I 
question whether the miner will find any relief through 
the exception of minerals in any future agricultural 
patents, by reason of the fact that such has been already 
ineffectually tried. Thousands of U. S. patents to agri- 
cultural land have already been issued with clauses ex- 
cepting the minerals, and yet no miner has been able to 
acquire title to the minerals contained in them. I refer 
not to the oil lands, which are frequently difficult of min- 
eral determination but to the thousands of acres of min- 
eral lands held by the Southern Pacific Co., and acquired 
by them as agricultural lands by means of sworn affi- 
davits as to their iron-mineral character. Aside from the 
exception of minerals contained in these patents, I main- 
tain that the title to the minerals in them has not and 
could not pass to the railroad company, for the reason 
that by an act of Congress, still in force, all mineral 
lands are reserved from purchase, sale, or grant, and can 
be acquired only under the mining laws, which require 
discovery, proper locating, assessment work, and the rest. 
In no other way can title to mineral lands be acquired, 
as provided by statute. Therefore, mineral lands held 
by any other shadow of a title are not legally held, and 



are open to location and to perfection of title by any 
citizen of the United States. The Government should 
lend every possible aid to the discoverer of mineral and 
protect his rights to the acquiring of these minerals 
where wrongiully claimed under patents issued for agri- 
cultural lands. 

Men are drafted, ships commandeered, steel and food 
prices regulated; why then should not the Government 
aid the miner in procuring title to mineral land when 
found on lands acquired through agricultural entry. If 
this class of land was patented as agricultural, and sworn 
affidavits were made as to its non-mineral character, why 
are so many portions of it being operated today for min- 
erals under mineral leases issued by the Southern Pacific 
Co. ? In order to protect innocent third parties who have 
already purchased some of these so-called agricultural 
lands from the Southern Pacific Co., why would it not be 
advisable for Congress to enact that, after a certain date 
the mineral portions of such so-called agricultural pat- 
ented lands should be open to discovery, location, and 
mineral patents issued in compliance with law.

A Plea for Labor 

The Editor : 

Sir — The discussions and editorials on labor, in your 
issues of November 17 and December 8, should be read by 
all who have anything to do with the handling of men. 
I agree, in the main, with what both your correspondents, 
J. F. Harrington and 'A Miner' write, but consider there 
is a field for the contract system in every mine, if this 
privilege is not abused by those in charge of operations. 
What 'A Miner' says about the old worn-out men being 
consigned to the scrap-heap, is, in many cases, only too 
true, and I can quite realize how he feels about the con- 
tract and bonus systems. "We are living in the age of the 
young man, and this applies especially to the Western 
States — an age when energy and the new science called 
'efficiency' are the chief factors; an age of getting things 
done, without stopping to consider what the ultimate 
results of the methods employed may be. There should 
be a place, and a good one at that, in any mine, for men 
like 'A Miner'; or are those that have passed the prime 
of life no longer of any use? Young men for energy, 
and old men for judgment and counsel, and a proper 
blending of the two is good to keep the balance. "The 
glory of young men is their strength ; and the beauty of 
old men is the gray head. ' ' 

The cost-sheet, which is the whip over the back of the 
superintendent, only tells part of the story ; perhaps the 
other part will remain untold until the great Book of 
Life is opened. We are laying too much stress on effi- 
ciency and the material side of things, and seem to forget 
that everyone has a right to a living, preferably in the 
occupation to which he has been trained, and if we are 
not careful, there is a danger of being caught and over-

whelmed by that wave of materialism which lias grad- 

Iually wrought such disaster to Germany as a nation — a 
nation that fills one with such dread and horror, thai 
even education, which, during the last decade has been 
looked upon as a panacea for all evil, is now being ques- 
tioned when one realizes what it has not done for Ger- 
many. "There is a reason", to use a phrase of one of 
our clever advertisers, why, in order to pass the local 
examinations of the great English universities, the can- 
didate has to "satisfy the examiners in the rudiments of 
faith and religion." A sound knowledge of other sub- 
jects, minus this, is futile. Perhaps they realize that 
even such an excellent thing as education requires a good 
foundation in order to withstand the stress of time and 
storm. 

When I was in New Zealand some years ago, most of 
the work in the mines, including the stoping, was done 
on contract, and I attribute the spread of this system, 
in preference to the wages system, to the scarcity of effi- 
cient shift-bosses. As Mr. Harrington points out, it was 
a case of getting contractors to do the supervision and 
the "driving". My experience of contracting has caused 
me to form the following conclusions : that the system has 
a tendency to eliminate the old and the unskilled men ; 
to increase the wages of the workers ; to decrease the cost 
of the work done. For such work as cross-cutting, shaft- 
sinking, and any work where valuable ore has not to be 
handled, I have always favored contracting ; but for 
stoping and driving on ore one needs a better guide than 
the cost-sheet to find out whether it is an economical 
system. I have tried stoping by the ton and by the 
fathom, sometimes with wages-men to take care of the 
ore, but would far rather do this work with wages-men, 
who have the company's interest at heart, even if they 
are old men that are getting beyond the energy of youth. 

The method of letting contracts is often much abused. 
A contract should be a contract, and binding on both 
sides. Prior to the establishment of the Arbitration 
Court in New Zealand, a mining contract was a somewhat 
one-sided document ; it was usually a list of printed con- 
ditions with spaces left out for filling in the specifications 
of the particular piece of work being let. One of the 
conditions was that the company could stop a contract 
at any time without compensation to the contractor, the 
excuse for this clause being that the workings might be- 
come inaccessible owing to water or bad air. At a meet- 
ing of employers, held during a serious dispute between 
the companies and the miners, I called attention to the 
unfairness of this 'no compensation' clause, and as an 
illustration, quoted the case of a party of contractors who 
had sent a long distance for their 'mates' and paid their 
traveling expenses, only to find that, after, about 10 
days, the contract was stopped. "When these ' Conditions 
of Contract' were investigated by the Arbitration Court, 
the Judge promptly objected to this particular clause, 
and it had to be eliminated. Another contract feature 
that the Court frowned upon was what is known as the 
'monthly take' system, which applies to driving and 
stoping let by the month. The union representatives 



were particularly bitter against ibis system, and, after 

bearing whole volumes of evidei the Qourt knocked it 

nut. The chief cause of complainl on the part of the 
men seemed to be that if they made good money one 
month they were cul down the next, and that the system 
gradually developed a species of 'soldiering'. At one 
large mine there was a system of letting large stoping 
contracts, usually taken by four to six men as contractors, 
these employing a sufficient number of wages-men to 
supply the required tonnage. These wages-men were 
paid more than the standard, as fixed by the Arbitration 
Court, but, notwithstanding their good pay, they de- 
veloped dissatisfaction because the contractors, who, they 
claimed, were doing just the same work that they were, 
made more money. They termed it "blood money" and 
said the contractors were growing fat out of their labor. 
This proves that in some cases men will have just as much 
of a grievance against each other as against overbearing 
'capital' as represented by a company. 

There are, of course, many men who will shirk and not 
do a good day's-work if they can avoid it, but I have 
always found that if one is fair it is possible to get good 
men, and with a combined system of wages and con- 
tracting there is a place for both the young and old. I 
do not agree with 'A Miner' that contracting, or even 
the bonus system, is necessarily 'killing' to the worker 
— nowadays we all have the 8-hour day, and I believe 
most men can stand 4 hours at a stretch, of even con- 
tract work, without harmful results, provided they have 
ventilation and other good working conditions. 

Young and selfishly ambitious superintendents and 
bosses sometimes abuse the contract system, and it is in 
this direction that the more elderly officials of a com- 
pany — the directors, for example — might give some 
supervision, using their judgment to curb the energy of 
youth. Any one who will read the story of Rehoboam 
and Jeroboam, as recounted in the 12th chapter of the 
first Book of Kings will realize that the counsel of young 
men sometimes lacks that wisdom which is essential to 
true success.

Flotation 

The Editor: 

Sir — I take pleasure in submitting to you some of the 
thoughts engendered in my mind by the perusal of your 
book on 'Flotation.' I have been interested more par- 
ticularly, as you know, in the precise function of oils 
when chemical additions are made to the pulp, and in 
the reasons for the different grades of concentrates re- 
sulting from the use of various brands of oils. 

Sulphuric acid may cause adsorption, say, of positive 
ions on the sulphide particles and consequently if the 
surface-concentration of the ions is sufficiently large, that 
is to say, if the critical contact-area is exceeded, the sul- 
phide particles will manifest an induced attraction for 
and a migratory tendency toward the negative bubble-

films, when the ions are firmly adsorbed. By 'critical' 
contact-area I mean that minimum area of contact be- 
tween two substances, A and B, beyond which one sub- 
stance A will impart to the other substance B its own 
polarity, that is, the polarity of A. This concept of the 
function of acid would explain directly the improvement 
in the grade of a concentrate, although I do not dis- 
regard its beneficial effect in wetting the gangue, affect- 
ing the degree of flocculation and the surface-tension, in 
cleaning the sulphide surfaces, and in altering the vis- 
cosity of the oiled films. Where acid is beneficial the 
use of lime may be detrimental by causing a different 
degree and kind of ion adsorption; both acid and alkali 
may have a good or ill effect by chemical inter-action 
with the pulp. 

When different oils are used the important causes of 
varying recoveries may lie in the different viscosities of 
the bubble-films, and in the varying degrees of adhesion 
of the oil to the sulphide particles. These two factors 
seem to merit most attention, although electro-static 
charges may in some cases be not without their influence. 
The grade of concentrate may depend also on mechanical 
manipulation of the flotation machine. With too thin a 
bubble-layer, that is, too high a pulp-level, fine gangue- 
particles may be literally bombarded over the lip of the 
cell. The use of a large amount of air has a similar 
effect, especially if the froth is at all viscous, for the 
finest gangue-partieles are projected into it and remain 
entangled there. The froth-cleaner cells should always 
have a thick blanket of froth, which is made to overflow 
gently, and the bubbles should preferably be somewhat 
brittle. This would give any granular gangue-partieles 
time and opportunity to slide back into the pulp. With 
a higher heading-value a better concentrate is obtained 
because, for one thing, the froth being more uniform, the 
cells are so much the easier to control. Then, again, with 
a comparatively rich feed, if much air is not being used, 
and if we have an oil that does not yield a voluminous 
froth, the grade must be higher, for the sulphide par- 
ticles being preferentially attached to and covering the 
bubble-film there is less exposed surface to which the 
finest gangue-partieles in the pulp can adhere. It seems 
to follow that the amount of froth that should be pro- 
duced is a function of the richness of the feed. I took 
some flotation-concentrate assaying 6% copper and re- 
floated one portion after adding sodium carbonate, and 
the other after adding sulphuric acid, obtaining two con- 
centrates of practically the same grade. In this instance, 
therefore, alkalinity or acidity of the pulp had, per se, 
no different influence on the results. The electrolytes 
may be assumed to have modified the bubble-films in the 
same way. 

Thinking that by baking the rougher-concentrate be- 
fore re-floating I might produce a markedly cleaner con- 
centrate, I tried the idea, but with no success. I should 
like to have an explanation of the following: Into a 
filtered solution (in an assay of copper by the cyanide 
method) I put a small drop of Barrett No. 4 oil and, at 
once adding the ammonia, shook the flask for a minute. 



The solution seemed to be quite clear. On adding one 
cubic centimetre of the cyanide solution a faint opal- 
escence appeared ; this, with further addition, developed 
into a dirty-green very fine precipitate, which was filtered 
off and the tiWation finished. A second assay was run 
without an addition of oil ; the results were : 

With oil 3.4 cc. KCN necessary 

Without oil 3.9 cc. KCN necessary 

In the former instance, was the copper included by the 
emulsoid as cuprous ammonium hydrate 1 

When a complete analysis of flotation-concentrate is 
desired I should like to point out something that is often 
overlooked. The froth should be broken down and well- 
washed with distilled water, otherwise to the legitimate 
sample there will be added the soluble salts that are pre- 
cipitated on evaporation of the solution. Where no pre- 
cautions are taken the assay-value, for example, for the 
alumina content may be fictitious, especially in froths 
derived from an acid pulp.

Heap Leaching of Copper-Sulphide Ores 

The Editor: 

Sir — I have read with great interest the long and 
interesting article on the above subject in the Mining 
and Scientific Press for November 24. While agreeing 
with the article as a whole, I beg to submit herewith one 
or two corrections. 

1. With regard to recovery, one is apt to read at the 
beginning of the article that 80% recovery has been 
demonstrated in actual work of eight months. If, as a 
result of the experimental work, the sentence, page 749, 
should read, "the entire process has demonstrated a 
'probable' recovery of 80% of the copper in the ore," it 
would be clearer. Of course the sentence at the end of 
the first paragraph on page 757 may make it perfectly 
clear to the careful reader that the 80% recovery is ex- 
pected in about two years. 

2. While admitting the possible formation of metallic 
copper in the heap, one must always remember that an 
increase of the same agent, Fe,(S0 4 ) s , that helped to 
produce the copper will also dissolve it, see the equations 
5, 6, and 8, page 755, and so this possible evil "dies a- 
borning. "

The Story of the U. V. X. Bonanza— II 



By T. A. RICKARD 



Now comes the question, how much of this was mere 
luek aud how much of it was due to inductive reasoning 
from good evidence? When one hears of a great mineral 
discovery one naturally asks whether luck or science was 
chiefly responsible. If it was luck, nothing much is to 
be learned; if science, then the evidence in the ease may 
prove useful to other explorers. In order to obtain an 
answer to this question, I made a study — such as a 



metamorphism the schist became partly crystalline and 
by shearing the diorite became schistose, so that today it 
is difficult to distinguish between them. The formation 
may be called a diorite-schist. Into this rock there pene- 
trated copper-bearing solutions, forming lenses of cop- 
per-pyrite at the contact of the schist and diorite. Thus 
the original copper ore was of pre-Paleozoic origin. 
Geologically the U. V. X. mineralization is of remarkable

journalist-engineer could make in two or three days — of 
the mine and its geologic environs. In making this in- 
quiry I was aided by Mr. Douglas, to whose hospitality, 
mental and physical, I am greatly indebted. 

The geologic structure of the Verde district may be 
outlined as follows: The basal rock is 'a schist, cor- 
related with the Yavapai formation of the Bradshaw 
quadrangle. This schist is geologically ancient, prob- 
ably of pre-Cambrian age. It is composed of meta- 
morphosed volcanic tuffs and flows, together with clastic 
sediments, which in the Jerome district are both argil- 
laceous and silicious. Into these consolidated oceanic 
sediments a batholith, or mass of intrusive igneous rock, 
was pushed. The batholith was granite ; from it tongues 
and dikes penetrated the sediments, which, by meta- 
morphism, became schist. The marginal phase of the 
granite was diorite; this intruded into the schist so 
freely as to constitute a large proportion of its bulk. By 



antiquity. On the basement complex, after it had been 
eroded by weathering, there was deposited, in late Cam- 
brian time, the sediment that now appears as beds of 
sandstone, and later still, probably in the Carboniferous 
period, a greater thickness of limestone. This series of 
rocks underwent the movements incidental to the adjust- 
ment of the earth's crust to its cooling and shrinking 
interior. Breaks were followed by intrusions of magma 
from underneath, forming more dikes and tongues of 
igneous rock. The substance of these was the felsite* 
and quartz-porphyry now exposed at the surface or 
underground. Where these dikes cut through the ore- 
bodies they have been kaolinized and bleached, and are 
known locally as 'watercourses.' Erosion modified the 
surface successively between these periods of sedimenta- 
tion and vulcanism. Upon the series of unaltered sedi-

ments that covered the earlier complex there overflowed, 
in Tertiary time, from a volcanic vent, a lava of the 
kind known in Arizona as 'malapai, ' a word derived 
from the Spanish mal pads, meaning 'bad land.' This 
is a rock of the basalt type. 

On referring to the U. S. Geological Survey's folio on 
the Bradshaw Mountains, published in 1905 and devoted 
to a preliminary description of the region, I find that the 
authors, T. A. Jaggar and Charles Palache, state that 
diorite "forms the west wall of the United Verde ore- 
body." This diorite they describe as "a basic border 
phase of the Bradshaw granite and is found chiefly on 
the borders of large masses of that rock along its contact 
with the Yavapai schist," where the granite has intruded 
into the schist. The sandstone and limestone at Jerome 
are said to be "outliers of the great mass of horizontal 
Paleozoic and Mesozoie sediments that form the high- 
plateau region of northern Arizona and New Mexico." 
The ore was precipitated from solutions following in 
the wake of deep-seated intrusives. Copper wes de- 
posited in fractures and in the crushed rock adjoining 
fractures or between them, and by substitution of the 
more soluble portion of the schist formation. The earlier 
mineralization was associated with the intrusion of the 
diorite, before the deposition of the sandstone and lime- 
stone. The main fact is that the ore is in the schist 
near the contact with the older intruding igneous rocks, 
but equally important is the belief, so fully confirmed by 
evidence as to have the value of a fact, that the rich ore- 
bodies of the United Verde and U. V. X. mines do not 
represent the mineral as deposited primarily, but they 
are enrichments of the original copper mineral through 
the addition of the copper brought down by percolation 
from above.* The primary mineral is chalcopyrite, the 
secondary is chalcocite. As the surface of the copper- 
bearing schist was weathered and eroded, the copper was 
dissolved by the ground-water and carried downward, to 
be re-precipitated as chalcocite, which covered and 
eventually replaced the chalcopyrite. This process of 
migration and concentration was not confined to a short 
space of time nor to a single geologic period ; it began 
soon after the primary ore was deposited, but the prod- 
uct now removed by the miner is the result of actions 
and reactions that have been at work from remote ages 
until today. 

It will be understood therefore that as this ore was 
formed in the diorite-schist, under the thick covering of 
younger rocks, there would have been no evidence avail- 
able to the miner if these overlying rocks had not been 
removed by erosion, so as to expose the deep-seated ore- 
's. F. Emmons, in 'The Secondary Enrichment of Ore De- 
posits.' Vol. XXX, p. 192, Trans. A. I. M. E„ speaking of the 
United Verde mine, said: "The physical conditions there more 
nearly resemble those of Butte than at either of the other local- 
ities [Bisbee, Globe, and Clifton-Morenci], and an underground 
study would probably have been most instructive. Unfortu- 
nately, the policy of the exclusion of visitors pursued by the 
owner was strictly enforced in my case, and I could only de- 
termine that rich sulphides do occur beneath the gossan." 



bearing formation. This exposure was brought about 
by faulting. See Fig. 4. 

In the U. V. X. mine, as we have seen, the schist and 
diorite are covered by 500 ft. of sandstone and limestone, 
and these in turn by a cap, 200 ft. thick, of lava. No 
sign of the rich orebodies exists at surface. Walking up 
the steep hillside the miner finds that the basaltic lava, 
or 'malapai,' ends abruptly; above a line, or band, of 
crushed rock running athwart the slope there appears 
the schist that contains the rich orebodies of the United 
Verde mine. Higher on the hillside there is a succession 
of sandstone, limestone, and lava — like the section ex- 
posed by the U. V. X. workings. The break between the 
upper and lower series, where the recent lava is now in 
contact with the old schist, marks the course of a fault. 
The town of Jerome is distributed along this fault, be- 
cause the scarp of it furnished footing for buildings. 
For two miles the course of this fault is N 37°W, for 
five miles it is N 53°W, but the strike varies widely, be- 
tween due north and N 60 °W. It is a corrugated sur- 
face, not a simple plane of movement. The dip of it is 
about 65° north-eastward near the Daisy shaft. It runs 
south-eastward from below the United Verde slag-dump, 
under the town, underneath the post-office, passing close 
to Miller's store, above the lower school-house, and nearly 
under the two upper school-houses; thence it drops into 
Deception gulch, where the shaft of the Calumet & 
Jerome mine is almost in it, but just above it. The 
vertical displacement produced by this dislocation of the 
earth's surface is 1700 ft. and the horizontal displace- 
ment is 900 ft. down-hill, that is, north-eastward. If re- 
stored to its former position the main orebody in the 
U. V. X. would be underneath the post-office of Jerome. 
Now it will be evident why the U. V. X. orebodies re- 
mained so long undiscovered. There was no sign of them 
at surface, there was no proof of a continuity of the 
United Verde orebodies into outside ground, and Senator 
Clark took pains to prevent others from obtaining any 
such information as would have encouraged systematic 
search. 

On May 21, 1917, Mr. Douglas took me underground 
in the U. V. X. mine. In the 800-ft. 7 station of the Edith 
shaft the sandstone appears, but 300 ft. southward and 
200 ft. westward the drifts penetrate diorite. This rock 
has a schistose structure and is not easy to distinguish 
from the true schist, which has been so metamorphosed 
as to resemble a diorite. Together these two rocks con- 
stitute the country-rock of the ore-zone. The principal 
orebodies appear to be adjacent to, and replacing, a 
series of later dikes, now much kaolinized and devitrified 
into felsite. Mineralization is intensive where this felsite 
traverses the contact of quartz-porphyry and diorite on 
the north side of the ore-zone; in short, the ore is found 
in a complex of eruptives the true relations of which can 
be determined only by aid of close microscopic study. I

am informed by Borace V, WincheU thai much of the 
supposed quartz-porphyry is only quartz. Mr. WincheU 
makes the illuminating suggestion thai the jasperoid 
quartz covering the orebodies and common elsewhere in 
the pre-Cambrian rocks is not a 'cap' nor a leached 
gossan, but a part of the original country-rock, in this 
respect resembling the jasper of the Keewatin series in 
the Lake Superior district. This quartz, he believes, is 
not veinstone but a silicious oceanic precipitate produced 
in pre-Paleozoic time.

crushed rock, consisting of mud and fragments, torn 
from the strata through which it has passed.

show that there is no more favorable place for the deposi- 
tion of ore than where schist has been fractured and 
penetrated by eruptives followed by thermal waters. Rio 
Tinto is an old example ; Miami is a later one. This fact 
has been linked, in hypothesis, with the big fault, but it 
is important to note that the fault cuts the basalt and 
therefore is post-Tertiary.f A tunnel on the Hermit claim, 
I am informed, cuts the fault and exposes the relation- 
ship just cited. Along the system of fractures the miner- 
alizing solutions were enabled to circulate and deposit 
their content of copper. The trend of the U. V. X. ore-

form near the smaller orebody at 1407. East of the main 
orebody the kaolinized roek includes several inches of 
chalcocite and on the west this vein of chalcocite sepa- 
rates the 'felsite' from 'quartz-porphyry. ' Only micro- 
scopic investigation can furnish data for a correct label- 
ing of these rocks. 

If one may be permitted to theorize on such slender 
evidence, I would say that the youngest kaolinized dike- 
rock was the chief agent in producing the concentration 
of copper mineral that we call 'rich' ore. The diorite is 
ore-bearing where crossed by this 'felsite,' particularly 
where the 'quartz-porphyry' contacts provided facilities 
for fracture. Such fracturing was intensified near the 
line of the big fault. Thus conditions favorable to ore- 
deposition were localized. The diorite-schist is pene-

trated by veins of quartz and iron-stained shear-lines. 
Along some of these copper is to be seen in oxidized con- 
dition, as carbonate. That brings me to the evidence 
that induced Mr. Douglas to spend a large sum of money 
in search for ore. 

Mr. Douglas was attracted, in the first place, by the 
iron-stained vesicular ('vuggy') quartz at the south end 
of the Fisher drift, on the hanging-wall side of the fault 
in the Daisy workings. Similar signs of ore were noticed 
by him in the north-easterly cross-cut, which for 270 ft. 
runs through decomposed iron-stained schist showing 
coppery stains along the planes of schistosity. Again, 
he was impressed by the patch of chalcocite ore cut in a 
raise at a point 100 ft. above the 800-ft. level. This also 
lay on the hanging-wall side of the fault, that is, on the 
side where he expected to prospect. The ore had been 
dug out, so that none of it was to be seen in place, but 
some of it remained on the dump, and he believed the 
statement concerning it to be true. He had a good gen- 
eral idea of the local geology and of the structural con- 
ditions produced by the fault. 

As I stood on the ridge between Mr. Douglas's house 
and the Edith shaft, I looked up the ugly hillside toward 
the United Verde mine and asked myself whether, hav- 
ing seen the evidence described to me by Mr. Douglas, I 
would have been inclined to spend my own money and 
my friends' in a costly search for a bonanza. Frankly, 
I have too little of the speculative temperament to have 
started the project in the big way in which Mr. Douglas 
carried it through, but if I had been engaged to advise a 
rich man in the matter, I would have told him to go 
ahead. Let me describe what an observant miner sees 
from the spot I have indicated : On the crest of the hill 
due west, above the Daisy shaft and behind the United 
Verde buildings, the level line of the white limestone 
makes an escarpment. The sandstone appeal's under 
the limestone, as can be ascertained by closer inspection. 
Just above the United Verde shaft-house one sees a big 
open-cut, or 'glory-hole,' in the diorite-schist underneath 
the sedimentary rocks. The slag-dump cuts across the 
hollow in which Bitter creek has its source. The fault is 
suggested by the break between the diorite-schist and 
the near ridge of malapai. Even an amateur geologist 
can follow the line of crushed rock marking the fault, 
which runs through a gap between the malapai ridge of 
Main Top hill and the higher slope on which the United 
Verde slag-dump rests. The fault crosses the hillside 
just above the Daisy shaft and under the stable on the 
left, south-eastward toward the town of Jerome. The 
bed of Bitter creek is a gully full of the detritus of the 
rocks above, washed from the outcrop of the fault. The 
malapai in front and to the right on Main Top hill has 
been eroded to a thin edge on the near or eastern slope, 
exposing the limestone underneath. Below the limestone 
the sandstone appears, and following the slope toward 
the Verde valley a series of horizontal limestone beds is 
uncovered, suggesting block-faulting. 

The relation of the beds of limestone and sandstone 
near-by to that of the similar series on the top of the hill, 



with a pronounced line of crushing and movement be- 
tween, is a plain indication of a fault. Above the fault 
tli ere had been found copper ore of extraordinary rich- 
ness and in large masses; why then should not similar 
ore be found *n the lower or hanging-wall side of this 
fault ? That seems an obvious question. Fisher answered 
it affirmatively and proved the courage of his conviction 
by starting to prospect in the Little Daisy ground. When 
Douglas took hold of the venture he could see what 
Fisher had seen on the surface, he understood the effect 
of the fault in dropping the ore-bearing zone, and he 
had the further evidence furnished by the patch of chal- 
cocite that Fisher had found in the Daisy workings. 
Small as it was, it sufficed to prove that the ore-making 
or copper-concentrating process had been at work below 
the fault. This evidence of secondary enrichment was 
highly important. Moreover the fault had been cut in 
the Verde adit 8 (called the Hopewell tunnel). It seems 
to me that on that evidence a group of rich men could 
afford to risk $225,000 in searching for ore. The ante 
was not too big for the game. 

I have not included the oxidized copper among the 
favorable signs. It had no immediate bearing on the 
problem. Such copper stains and patches of carbonate 
ore were mere humo de cobre, as Mr. Douglas, out of 
his familiarity with mining on the Mexican border, calls 
them. They were quite different from the hilos de cal- 
cocita, or threads of chalcocite, that indicate secondary 
enrichment. Such oxidized copper has been precipitated 
probably from the water draining down-hill from the 
outcrop on the United Verde ground, coming down Bitter 
creek and seeping into the lower ground. On the other 
hand, the silicified rock poor in copper, but still stained 
by it, might represent the upper portion of an orebody 
the copper from which has been leached for the benefit 
of the bonanzas in the deeper zone. It is probable, how- 
ever, that such a conventional explanation would be 
wrong. The copper stains are exogenous not endogenous, 
as Posepny would have phrased it ; they came from out- 
side and are not remnants of copper the rest of which 
has been removed by leaching. It is likely that seepage 
from above explains the presence of the precious metals 
in the copper ore. In the Copper Chief mine, on the out- 
skirts of the Jerome district, an enrichment with gold 
and silver is traceable to the overlying limestone. It is 
probable, as Mr. Winchell suggested to me, that carbon- 
ated waters from the limestone brought gold and silver 
into the gossan formed by the weathering of the masses 
of copper ore in the United Verde, but not in the U. V. X. 
mine, since the latter was enriched for the most part in 
pre-Cambrian time, before the limestone was laid down. 

The bonanzas are now three or four hundred feet below 
the former surface of the schist. They were formed by 
the enrichment and alteration of the quartz, pyrite, and 
chalcopyrite of the primary ore. Where oxidized they 
show residual limonite and appear like the vesicular 
copper-stained quartz on the 800-ft. level of the Daisy

way to the smelter at Clarkdale in the Verde valley.

workings. The erosion of the fault-escarpment, contain- 
ing broken fragments of ore. would cause copper to be 
dissolved in the water of Bitter creek. On the upper 
side of the fault a large tract of Cambrian land-surface 
has been eroded, removing part of the ore-zone, and some 
of the copper that was in it may have been washed down- 
ward to enrich the other and intact part of the ore-zone 
that was preserved under the sedimentaries and under 
the cap of lava. Whether mineralizing solutions from 
the schist followed fractures into the overlying limestone. 
and there formed orebodics by replacement, is a nice 
question. Some of the ore found, for example in the 
Dundee & Arizona mine, may be of this character, but as 



"ivlui.lv must have occupied a position underneath the 
! M >>-< oilier in .In-time, and the main ore body must have 
lain still farther from the United Verde. The orebodies 
in the two mines are not projections of each other; they 
are connected not on the dip but on the strike of the ore- 
channel, which does not coincide with the fault. There 
was a connection of mineralized ground along the strike 
in this ore-channel, and it was disrupted diagonally by 
the fault. The fault itself dips more flatly than the ore- 
channel and they should intersect in the U. V. X. ground 
at a depth of about 2000 ft. That disposes of the possi- 
bility of apex litigation. 

The heavily sulphurous character of the ore presents

to that I do not know. When copper has been found, 
whether as carbonate or sulphide, in a given spot, it is 
not possible off-hand to say whether it was precipitated 
by ascending or descending waters, but the answer to 
such a question can be made after careful investigation, 
and it furnishes information of immediately practical 
value to the prospector. In the United Verde both chalco- 
pyrite and bornite are found down to 1800 ft., that is, far 
below the chalcocite zone of secondary enrichment, which 
has yielded bonanza stopes for a vertical depth of 800 
feet. 

Next comes the question of the connection between the 
United Verde and the U. V. X. orebodies. In the first 
place, the latter is not a part of the former, that is, if the 
ground were restored to its former position, as it was be- 
fore the faulting, the U. V. X. orebodies would not con- 
nect with those of the United Verde. Originally the 
U. V. X. ore was higher than that of the United Verde. 
Before the ground was faulted the smaller (or 1407) 



a danger against which the management of the U. V. X. 
mine must guard systematically. A forcible reminder 
exists already. In approaching the 1407 stopes, in the 
smaller orebody first discovered, the temperature rises 
rapidly to 103° F. Farther it is not safe to go, the heat 
and gas being dangerous. Iron wire, broken ear-wheels, 
and other scrap have been thrown into the ditch along- 
side the track, so that the water issuing from the burn- 
ing ore may precipitate its copper. After passing over 
this scrap-iron the water is neutralized by the addition 
of lime carbonate so as to destroy the acidity, which other- 
wise would corrode the pump-line. Combustion has been 
started by caving. The stope was carried five sets above 
the level, the ground being held by square sets filled with 
waste, except at the working end, which was two sets 
wide and two sets high, not filled. A round of holes was 
shot in ore at 11.30 one morning and indications of cav- 
ing were visible when the men returned to work after 
the noon interval. The men were withdrawn immediately

and at 3 p.m. the whole east side and the back of the 
stope collapsed, crushing the timbers all the way down to 
the sill-floor, the height of five sets, or 41 ft. The rise in 
temperature became sensible in a few days. The cave 
started four sets above the 1300-ft. level and dropped 
the ground 8 ft. This was enough to develop sufficient 
friction to cause combustion in an ore containing 28% 
sulphur, according to reactions utilized in converting 
matte where there is iron sulphide that is readily oxidiza- 
ble in association with copper sulphide. The misfortune 
was hastened by the fact that the rich copper ore dipped 
at an angle of 60° and had an overburden of crumbly 
pyrite. The block of ground 'on fire,' that is, in a state 
of smothered combustion, contains 2000 tons of 30% ore. 

The neighboring United Verde mine has suffered 
severely from this cause. The first fire, in 1894, was due, 
as in the case just cited, to spontaneous combustion fol- 
lowing a cave. As it could not be extinguished, the place 
first affected was bulkheaded so as to prevent a spread- 
ing of the fire, but even this was not done completely, 
therefore "the smoke and gas worked its way over the 
orebody on the different levels and cut off a large pro- 
ductive area of high-grade ore," as Robert E. Tally, 
the superintendent has related. 9 Two other fires started, 
doing great injury to the mine. An attempt was made to 
extinguish the combustion by flooding with water, but 
this failed, the air inevitably finding its way to the burn- 
ing ore. Then carbon di-oxide gas and steam were tried, 
in turn, but in vain. It was found impossible to shut off 
the parts affected so as to apply these remedies effectively. 
In 1905 the plenum system was introduced. This con- 
sists in forcing air against the gas generated by the com- 
bustion ; an air-pressure of 2 to 5 lb. suffices to keep back 
the gas and cool the ground sufficiently to render mining 
possible. Mr. Tally states that by this method the tem- 
perature was reduced from 1200° F. to 120° F. in about 
six weeks. Gradually, by ventilation, the temperature 
was lowered to 75°. The air forced into the hot stopes 
now finds an outlet through raises in the foot-wall direct 
to the surface, so that the gas does not penetrate the 
upper workings. The current of air is regulated by doors 
connecting with the stopes at successive levels. 

To extinguish a mine-fire is satisfactory; but to pre- 
vent one from starting is better. The mass of low-grade 
pyrite on the hanging-wall side of the rich ore at 1407 
was so loose as to run like sand ; it was separated from 
the chalcocite by two feet of soft decomposed rock, so 
that the conditions were peculiarly treacherous. Exactly 
similar conditions may not be repeated elsewhere in the 
mine, but something like them has to be faced in other 
parts. The ore-ground is exceedingly 'heavy,' in the 
miner's sense, as it is also in terms of specific gravity. 
Seven cubic feet of ore weighs a ton. The chalcocite 
breaks in slabs ; it is brittle ; it breaks readily ; in stop- 
ing, a few 'pop shots' suffice. To prevent 'runs,' the ore 
has to be bulkheaded continually.

United Verde Copper Co.' Trans. A. I. M. E., Vol. LV, pp. 
1S6-200. 



Mr. Douglas and Mr. Kingdon are fully alive to the 
perils of fire in ore of this character. To safeguard the 
mine it is proposed to make barriers across the big ore- 
body. A cut 12 J ft. wide will be carried through the ore ; 
this w 7 ill then be filled with waste from the surface. Any 
waste used for filling should contain less than 3% of 
sulphur. Thus a fire-proof barrier will be formed. Other 
barriers will follow at 25-ft. intervals. The cost of any 
such protective method is unimportant in such rich ore as 
compared with safety and completeness of extraction. 
The ore is so rich that it must be removed cleanly. 

Good ventilation is another prime requisite ; therefore 
the Daisy shaft is used as an upcast, so that fresh air 
comes down the two working-shafts. The new, or Con- 
crete, shaft is 250 ft. east of the Edith ; it was sunk only 
170 ft., the rest being done by raising from the different 
levels. An ore-pocket to hold 1000 tons of each of the 
two classes of ore is to be made between the 1100 and 
1300-ft. levels ; this pocket will discharge into 30-ton cars 
driven by an electric-storage motor through an adit, 
11,200 ft. long, which enters on the 1300-ft. level. The 
mouth of the adit is i$ miles from the smelter, to which 
the ore will be delivered on a 1.7% grade and 4° curves. 
The smelter, designed by A. G. McGregor, will have a 
capacity of 1000 tons of ore and is to be finished in 1918. 
Then the U. V. X. mine will be equipped for steady 
production. 

Manganese in Arkansas 

The high prices for manganese ores have stimulated 
interest in the little-exploited manganese deposits of 
west-central Arkansas. These deposits are found at in- 
tervals in a belt 4 to 12 miles wide, which extends west- 
southwest from Pulaski county, at the centre of the 
State, to Polk county, on its western border. The de- 
posits have been worked only in a small way and have 
produced but a few hundred tons of marketed ore. The 
ores consist of the four oxides, psilomelane, pyrolusite, 
manganite, and wad, the first three forming the larger 
part of the ores. Although these minerals may be found 
separately, two or more are generally intimately mixed 
in the same deposit, and at some places they are asso- 
ciated with iron oxides and manganiferous iron ores. 
The manganese ores occur as nodules, pockets, and short 
irregular veins from a fraction of an inch to 4 ft. thick, 
though veins 4 ft. thick are rare. The orebodies are 
scattered through the hard Arkansas novaculite and can 
doubtless be found on every mountain where the nova- 
culite is exposed. They occupy bedding planes or joint 
cracks, or form a cement in a novaculite breccia in 
which the rock fragments range in diameter from a frac- 
tion of an inch to over a foot. Most of the ores contain 
too much phosphorus for use in the manufacture of 
ferro-manganese, and too much iron for use in chemical 
industries and electric batteries, and where the quality 
is suitable for these purposes the quantity is generally 
too small for profitable mining.

Hoisting 'Ropes 



By M. H. SIGAFOOS 



"Until recent years it was generally conceded that the 
foreign steels for the manufacture of wire-rope were by 
far the best, due principally to the fact that Swedish 
ores, considered the finest the world affords, are em- 
ployed as their basic foundation. Such foreign steel as 
is imported by the American manufacturer for wire- 
rope purposes, is made to meet rigid specifications, in- 
suring as nearly as possible a uniform quality, and is 
carefully tested and analyzed to insure correct per- 
centages of manganese, silicon, and carbon, as well as the 
great necessity of their being extremely low in sulphur 
and phosphorus. Both of the latter elements are detri- 
mental to the production of wire to be used in the manu- 
facture of wire-ropes. Acid open-hearth steels are ad- 
mitted to be better than basic open-hearth and it has 
been suggested that this is due to the higher oxygen 
content in the basic steel. Much has been claimed for 
the qualities of chemically treated steels, such as vana- 
dium, chromium, and others, and in many instances they 
have proved the claims made for them, but for use in 
wire-rope they are still in the experimental stages, and 
no data are available at this time. 

Wire made from steels intended for the manufacture 
of wire-rope for ordinary purposes is divided into three 
classes, namely : Iron, with a breaking-strain of approxi- 
mately 80,000 lb. per sq. in. ; cast-steel, often erroneously 
called crucible-cast, which has a breaking-strain of 170,- 
000 to 180,000 lb. per sq. in. ; and plough-steel, with a 
breaking-strain of 200,000 to 250,000 lb. per sq. in. 
Wire is often drawn to a considerably higher tonnage, 
but this is rarely used for any other purpose than for 
standing-rigging on racing-yachts, where maximum 
strength, with the lightest possible weight, is essential, 
such wires are sometimes drawn to 260,000 lb. per sq. 
in. Very small sizes of wire-rope or strands for aero- 
plane-guys are drawn to even a higher tonnage. 

There has been much discussion on the point as to 
when a wire-rope has reached the end of its usefulness, 
and when it should be removed. Up to the present time 
it seems the question remains unanswered. 

After an exhaustive investigation of the bending and 
load-stress, conducted by the Bureau of Standards, a 
report was published, as Bulletin No. 75, stating in sub- 
stance, that a rope should be removed after a certain 
number of broken wires appear in each of the strands. 
The tables in the report undoubtedly have been compiled 
from stated loads, speeds, head-sheaves, and drum- 
diameters; from shafts of various depths, and, taking 
into consideration the torsional and load-stresses, they 

*Abstract of paper read before the Mining Section of the 
National Safety Council. 



form a useful guide. However, us their is no standard 
of sheave and drum-diameters, except those recom- 
mended by rope manufacturers, nor any set rule for 
maximum loads, it is evident that with each variation 
in the diameter of sheaves or load, so will the bending- 
stress and the load-stress vary. Both of these stresses 
are of great importance and have a direct bearing ou 
the factor of safety. In the catalogues of the wire-rope 
manufacturers are to be found the 'proper working- 
loads' of wire-ropes for the given sizes and grades. This, 
in almost all cases, is approximately 20%, or about one- 
fifth of the appromixate breaking-strength of the rope, 
and would appear to be a factor of safety of five. This, 
however, is not the case, as will be shown, and it is im- 
portant, in calculating the proper rope for a certain load 
with a required factor of safety, that this proper work- 
ing-load should not be confused with the actual factor 
of safety. While the working-loads do not show approxi- 
mately one-fifth of the breaking strength of the ropes, it 
does not by any means indicate that in operation the 
rope selected would have a factor of safety of five, due 
to the fact that in addition to the working-load, there 
are other stresses to he considered, the most important 
of which is the stress due to bending over the sheaves 
and drums. 

If the rope to be used is operated over standard-size 
sheaves and drums, the general average of bending- 
stress equals about 10% of the approximate breaking- 
strength of the rope. For instance, in a east-steel wire- 
rope 1 in. diam., composed of 6 strands and 19 wires to 
the strand, the approximate breaking strength of which 
is 30 tons, showing a proper working-load of one-fifth, or 
six tons, te be used on a minimum size sheave or drum of 
four feet, the bending-stress would be 2.70 tons, or nearly 
9}%, of the approximate breaking-strength of the rope. 
It is thus evident, that, by adding this 9J% to the load- 
stress, which is 20%, we have utilized 29-} of the ultimate, 
and instead of an apparent factor of safety of five, we 
actually have only 3.41, or less than 3|. This is still 
further reduced by the stress due to starting the load. 

It is often impracticable to utilize the size of sheave 
or drum recommended by the manufacturer. In such 
cases the bending-stress will vary inversely as those 
diameters are greater or less. Assuming, in the above 
example, that two-foot diameter sheaves were used, the 
bending-stress would be 5.58 tons, or about 18f % of the 
breaking-strain; this, in addition to the working load, 
would be 38f% of the ultimate strength of the rope, 
reducing the factor of safety to 2.6. The total working- 
stress then would be greater than one-third of the ulti- 
mate breaking-strength of the rope when new and is not

considered good engineering practice. If sheaves twice 
the diameter of those recommended by the manufac- 
turers, or 96 in., were used, the bending-stress would be 
only 1.4 tons or about 4J% of the ultimate strength of 
the rope. By reducing the bending-stress to a minimum 
more economical service could be obtained, and in many 
cases a smaller diameter of rope could be applied, thereby 
increasing the efficiency of the rope, and promoting a 
saving in first cost. 

Reverse-bends play an important part in the early let- 
down of a wire-rope. The underwind rope, in which 
there are reverse-bends, will invariably give a shorter 
service than the overwind rope. The difference in serv- 
ice of the two ropes varies, but from experience the 
overwind rope will give 10 to 25% more service. The 
underwind rope, as it comes off the head-sheave, has 
taken somewhat of a set, the permanence of which de- 
pends on the relation of the rope-diameter to the sheave- 
diameter ; the smaller the sheave the greater the set. The 
rope now travels to the take-up drum, some distance 
away, and will wind in the opposite direction to that in 
which it came off the head-sheave; thus a reverse-bend 
is thrown into the rope, and, consequently, into the 
wires themselves. The rope cannot recover itself in 
most cases, for the set it received by the head-sheave is 
not entirely overcome before it strikes the take-up drum 
and consequently the effect of the latter bend is more 
severe. 

Another cause for failure of wire-ropes can be at- 
tributed to repeated shocks. The effect of these over- 
strains, as they may be called, is shown by microscopic 
examination of the metal as leading to crystallization 
with a consequent embrittlement of the steel. The over- 
lapping of the rope on the hoisting-drum, with occasional 
slipping of the top layer into the grooves made by the 
layer underneath, will, first, cause jerks which increase 
the load on the rope by an amount depending upon the 
slack between the drum and head-sheave, and, second, 
the inner series of wires will crush somewhat from the 
squeezing between the top and bottom layer and will 
assume a pear or bell-shape. 

In this condition it is impossible for the inner wires 
to perform their proper function, and the outer wires 
will be forced to take more than their share of the 
stresses. They will assume the shape of their cushion, 
the inner series, causing trouble in the form of abrasion 
on themselves. Overlapping cannot be eliminated in 
most cases on account of the amount of rope that must be 
taken on the drum, but the point to emphasize is the 
fact that frequent inspection must be made in order to 
minimize accidents. 

There are several methods of fastening ropes to the 
load, either by means of sockets or clips. Both of these 
can be made in such a manner as to break the rope before 
the connection gives out. In using sockets it was for- 
merly thought necessary to turn in or bend back the 
strands or wires into the basket of the socket. This 
method is now replaced by opening the wires in the 
strand of the rope that is to be socketed, thoroughly 



cleaning them with muriatic acid cut down with zinc, 
and pouring molten spelter on the straight wires. Tests 
of this method of socketing have proved that a more 
uniform strain on each individual wire can be depended 
upon. It necessitates great care and there is no possible 
means of inspection. The connection made with clips, 
if properly applied, is equally strong, and careful in- 
spection can always be made. This connection should 
be made with the U-bolt section of the clip over the 
short end of the rope. This insures greater safety, as 
there is no indentation on the main section of the rope 
by the U-bolt. 

Uses of Nitre-Cake 



Nitre-cake is the product resulting from the reaction 
between sodium nitrate and sulphuric acid in the nitre- 
pots at sulphuric-acid works. These chemicals when 
combined and subjected to the heat of the sulphurous 
gases from either the pyrite or the sulphur-burners, 
evolves the nitrous fume necessary for the oxidation of 
the S0 2 in the gases to S0 3 . The resultant liquor in the 
nitre-pots, on being discharged into the air, solidifies 
and is then called nitre-cake. Theoretically it should be 
acid sodium sulphate (NaHS0 4 ), but actually it gener- 
ally contains about 78% of that salt with 18% of Na 2 S0 4 , 
and about 4% moisture. As an acid reagent it is equiv- 
alent to about 32% sulphuric acid, and the saturated 
solution corresponds approximately to 18% H 2 S0 4 . The 
acid sodium sulphate, which is a waste-product from the 
manufacture of sulphuric acid, can be used as a substi 
tute for that material in many industries, and thereby 
help to economize on this commodity, so essential in the 
making of munitions, fertilizers, and a thousand other 
necessaries of modern civilization. Indeed, the acid 
sodium sulphate, which can now be had at many places 
for the cost of hauling it away, may be used directly in 
compost-heaps with raw ground phosphate rock, thereby 
converting it to soluble phosphate and leaving a sulphate 
of soda that is in itself beneficial as a fertilizer on many 
soils ; it is valuable also for removing oxide and scale from 
articles of iron or steel, such as castings, forgings, pipe, 
bolts, nuts, and rivets, and from sheet-metal for galvan- 
izing; it is useful as an acid wash, as a cream of tartar 
substitute for baking powder, as a bleaching agent in 
paper manufacture, for the production of hydrochloric 
acid by reaction with common salt ; and for a large num- 
ber of other purposes. It is the most practical substitute 
for sulphuric acid that is available, and its utilization is 
a matter of national concern. 

North Carolina, at the present time, produces about 
1300 oz. gold and 700 oz. silver per annum. Copper to 
the extent of about 10,000 lb. is produced from Gran- 
ville and Rowan counties. The possibilities of the State 
are much greater but development is retarded in part 
by difficulties over land-titles and still more by an exag- 
gerated idea among the people as to the value of un- 
developed mineral land.

AHMEEK STAMP-MILL 



CALUMET SHAFT NO. 5 



The Lake Superior Copper Country 



By HOMER GUCK 



The development of copper mining in the United 
States is as synonymous with the operation of the Calu- 
met & Hecla as it is with the expansion of electricity. 
How the great Calumet conglomerate lode was discovered 
is still a matter of dispute. People in Michigan continue 
to believe that 53 years ago old man Royale's boarding- 
house pig stuck his snoot into the Indian pit in the back 
yard of his road-house and unearthed a cache of copper. 
That was the story as told by B. J. Hulbert, the dis- 
coverer. 

The fact remains that the discovery of the great con- 
glomerate was due to mere chance. Hulbert was survey- 
ing a state road from Copper Harbor, the most northern 
point in the State of Michigan, to the south-west limit 
of what is now Houghton county. Royale's boarding- 
house was on the site of the Miscowaubik Club. It was 
a halt for overland passengers from Houghton to Eagle 
River, then the two larger towns. Centuries before, the 



Indians, having dug their mass copper from Isle Royale, 
started south for the winter. Desiring to avoid Ke- 
weenaw point, they went overland through the penin- 
sula and were caught by an early winter. They dug a 
pit and buried their copper. Their pit happened to be 
right on the hanging wall of the conglomerate lode of the 
Calumet & Hecla and the present location of No. 1 shaft, 
Calumet mine, still in operation. The surmise is that 
George Agassiz, son of the late Alexander Agassiz, for 
many years the president and directing head of the 
property. The Indians never returned for their copper. 
In the 17th century French explorers found copper on 
the Ontonagon river. This district was a virgin forest 
73 years ago when the Chippeway Indians ceded it to 
the United States. Twenty years before the Civil War 
there was a copper boom, which subsided and left a few 
small mines in the forests then covering this part of 
Michigan. The search then was for mass and boulder

copper. It was in 1858 that Hulbert made his discovery. 
At first he thought he had an old Indian mine. In ex- 
amining the surface he found the conglomerate outcrop 
just south of the cache at what is now No. 1 Hecla shaft. 
This big block of conglomerate was wonderfully rich. 
Hulbert was unable to buy the tract at Hecla, but, keep- 
ing his discovery quiet, secured the Calumet property. 
He sank his first shaft at what now is No. 4 Calumet, and 
in the middle of September 1864 opened the conglom- 
erate. Later he associated himself with Quincy A. Shaw 
of Boston. That gentleman furnished the funds by 
which the property was secured from the St. Mary's 
Mineral Land Company. 

At the time of the Civil War the production of copper 
in the world was insignificant, the Rio Tinto mines of 
Spain producing the largest part of it. The metal sold 
as high as 52 cents per pound. At that time Michigan 
was just coming into prominence, the output being con- 
fined to so-called 'float' copper and masses found near the 
surface and handled directly in a smelter. The Quincy 
mine was then our largest producer. It got out two 
million pounds in one year. The Calumet & Hecla pro- 
duces that much in three days now. By the way, the 
Quincy has paid dividends to its shareholders continu- 
ously from that time to this, missing just one year, dur- 
ing the Western Federation strike in 1913. 

With the discovery of the Calumet conglomerate the 
whole system of getting out copper changed. In this dis- 
trict the conglomerate carries the copper in its pure state 
in particles from as small as a pin-point to the size of a 
fist. The Calumet conglomerate lode has paid at least 
$150,000,000 in dividends to the shareholders of the Calu- 
met & Hecla Corporation, and over $300,000,000 in wages 
to thousands of employees and indirectly for mainten- 
ance and operation. In the early days the Calumet & 
Hecla ore was very rich. Each year it is becoming leaner. 
Some idea of the industrial problems this corporation 
has met and overcome may be gained from a brief ex- 
planation of the operation. First you sink your shaft, 
equip your plant, build your stamp-mill and smelters. 
All these things cost millions. But forget them. They 
are up and operating. Now to get copper out of the 
ground the miners go down a mile from the surface, 
then as much as half a mile from where they left the 
skip to the place where they operate a drill for six hours, 
punching holes into the copper-bearing rock. The holes 
are filled with powder and the ore blasted down. This 
ore, locally called 'rock,' is put into cars, pushed to 
the shaft, and dumped into the hoisting-car, or skip, to 
be hauled a mile to surface. At the top of the shaft the 
skip is dumped again and the ore goes through a series 
of crushing processes in the shaft-house itself, after 
which it is fed into cars to be hauled five or six miles to 
the stamp-mill, where it is dumped again, crushed into 
small pieces by stamp-heads having a pressure of five 
tons, jigged and crushed and rolled and washed on in- 
numerable tables, re-ground again, and finally put 
through an acid and flotation process to prevent the 



escape of the smallest particles of copper. Then the 
concentrate of native copper is hauled another mile from 
the mill to the smelter, where it is roasted, treated by 
electrolysis, and cast into cakes or bars or slabs, as the 
customer reqftires. Most of it is shipped to New York. 
For every ton of ore that is blasted down in the mine — 
for every 2000 pounds — there is extracted just 20 
pounds, or 1%, of copper. The remainder, 1980 lb., 
goes into the lake. 

To the reader of this technical magazine these state- 
ments sound like the elementary instruction of a mining 
college. I am telling it just as I do to every committee 
from the southern farming or city district of the lower 
peninsula of Michigan when they come to visit us and 
want to see a mine. They have no conception whatever 
of the enormity of the problem that takes a speck of 
copper from a point a mile or two from surface and puts 
it down on the New York dock at a profit ; and too often 
our high-grade technical engineer passes over these de- 
tails without a thought, giving no consideration to the 
things that are so obvious to him, accomplishments in 
which he himself has taken a part ; accomplishments that 
are so much a matter of reality that he fails to appre- 
ciate their importance because of their familiarity. 

A year ago all this was done at a cost of ten cents per 
pound. Now the cost is higher, probably 13 cents. That 
is due to the rise in wages and the increased cost of every- 
thing that is used in the operations. The Calumet & Hecla 
for itself and ten subsidiaries, employing 14,000 men, has 
just announced a continuation of the 10% bonus and the 
5 cents per diem increase in pay for another six months. 

In the early days richer ore closer to surface was 
worked. Then the miner got 100 pounds from every ton, 
and lost 30 lb. in the stamp-mill, and thought nothing of 
it. Now this old tailing is being worked over again and 
it is paying better than a new mine. That fact alone 
illustrates the metallurgical progress made at this won- 
derful mine. With the greater depth, with the leaner 
ore, it has been a man's problem to keep this great cor- 
poration up to its standard of earning capacity. And 
the man who took charge of this property when it seemed 
to be going the way of all mines was a Michigan product, 
James MacNaughton, now the first vice-president of the 
company. Today the total cost of mining and of bring- 
ing the ore to the surface through a mile or two of work- 
ings is one dollar per ton. And the miners are the best 
paid workmen in the world. Today their average wage 
is $5 and many of my miner friends are cashing con- 
tract checks that run better than $250 per month. 

But the most wonderful thing about the Calumet & 
Hecla is its paternalism. When we had a strike here a 
few years ago, the only one in the history of the enter- 
prise that amounted to anything, the cry of too much 
paternalism was raised. But it failed, as did the last 
dying effort of the Moyer-Mahoney gang of Western 
Federation agitators. The paternalism is not ostenta- 
tiously displayed, but it is none the less practical and 
effective. It gives the Calumet & Hecla the finest class 
of miners to be found anywhere.

Sulphur 30.0 " 

Nickel 3.5 " 

Copper 1.2 " 

Gold 0.01 oz. per ton 

Platinum 0.01 " 

Silver 0.29 ' 

By the present method of reduction both the iron and 
sulphur are wholly lost, and when we consider that 70% 
of the nickel is used for alloying with steel to form 
nickel-steel, the wastefulness of the process is at once 
evident. It has long been the dream of the metallurgist 
to discover a process by which this waste can be avoided. 
The difficulty in the past has been threefold; first the 
complete elimination of the sulphur, second the rooted 
objection of metallurgists to the presence of copper in 
the resulting steel, and third the loss of the precious 
metals, which, of necessity, go into the pig, and hence 
into the steel. The first two of these objections have 
now been overcome. By improved methods, the sulphur 
content of the pulverized ore can be reduced to less than 
0.5% by roasting in a Wedge furnace, and if, after smelt- 
ing, the resultant pig is converted into steel in a basic- 
lined electric furnace the sulphur content of the steel is 
negligible. It is freely admitted that copper in excess of 
0.75% will make steel red-short, for the reason that steel 
will not dissolve a greater amount, and the copper sepa- 
rates. But recent researches on nickel-copper steel alloys 
have demonstrated that when both nickel and copper are 
added to steel, if the ratio of copper to nickel is less than 
1 : 3 the copper does not separate and consequently red- 
shortness does not ensue. This is readily explained by 
the fact that nickel is a solvent for both iron and copper 
and consequently holds the latter in a solid solution in 
the steel. It has been found, for instance, that 3.5% of 
monel metal, which contains 69% nickel, 29% copper, 
and 2% iron, added to steel makes an alloy substantially 
the same in mechanical and other properties as a 3.5% 
nickel-steel. The third objection, that of the loss of the 
precious metals in the pig, has not, and, from the light 
of our present knowledge, will not be overcome, but the 
loss is more than offset by the gain of the iron and of the 
cheaper metallurgical treatment. Besides, the precious 
metals are now lost in the manufacture of monel metal, 
and, at any rate in part, by the Orford process of re-

fining, as is proved by their presence in many of the 
International Nickel Co.'s products. 

The first attempt to produce nickel-steel directly from 
the Sudbury ores was made by E. J. Sjostedt more than 
ten years ago, at Sault Ste. Marie, under the auspices 
of the Canadian Department of Mines. A low-content 
nickel ore was selected with the view of keeping the 
nickel content of the pig as low as possible. The roasted 
ore contains 2.32% nickel, 0.41% copper, 45.8% iron, 
and 1.56% sulphur. The charge employed consisted of 
400 lb. of ore, 105 lb. charcoal, and 40 lb. limestone. 
This was smelted in an electric furnace, and the result- 
ing pig contained 4.1% nickel, 0.7% copper, 0.006% 
sulphur, 0.04% phosphorus. In all 14,500 lb. of ore was 
smelted and 7336 lb. of pig metal was produced. The 
power consumed was 0.39 hp-yr. per 2000 lb. of pig 
produced, and the charcoal consumption was 55% of the 
weight of the metal obtained. Later, under Sjostedt's 
direction, 168 tons of nickel-copper pig was produced at 
the rate of 1.34 tons per day in an electric furnace at 
Sault Ste. Marie. Some of this was converted into steel 
in a Heroult furnace at the plant of the Halcomb Steel 
Co. To reduce the nickel content and make the resulting 
steel comparable with standard 3.5% nickel-steel, scrap- 
steel had to be added to the charge. The following are 
the results of chemical and physical tests of the copper- 
nickel steel, and for comparisons tests made at the same 
time of open-hearth nickel-steel:

These results, it will be seen, are in favor of the nickel- 
copper steel, for while the tensile strength is slightly less 
than that of the nickel-steel, the elongation is consider- 
ably greater. This may be due in part to the fact that 
it was made in an electric furnace, while the nickel-steel 
was made in an open-hearth furnace, but, be that as it 
may, the nickel-copper steel stands up to the require- 
ments of a 3.5% nickel-steel. Still, notwithstanding the 
favorable tests, metallurgists refused to accept nickel- 
copper steel for structural purposes; it was barred in 
most specifications, and at the time of his death, Sjostedt 
was working out a process for the economical removal of 
the copper prior to smelting the roasted ore. 

At the request of the Royal Ontario Nickel Commis- 
sion, Alfred Stansfield repeated Sjostedt 's experiments 
on a laboratory scale at McGill University and to a great 
extent corroborated his results. Mr. Stansfield did not 
produce as good a steel as that obtained by the Holcomb 
Steel Co., but, considering that he was working on a 
laboratory scale with charges that produced only from 
14 to 20 lb. per pig, it was hardly to be expected. The 
following are the physical tests on the steel produced at 
McGill: 

Elastic limit, lb. per sq. in 70,100 

Yield point, lb. per sq. in 77,400 

Maximum load, lb. per sq. in 101,500 

Elongation in 2 in., per cent 18 

Reduction in area, per cent 31.9 

Many metallurgists still retain this prejudice against 
copper in steel, even in the face of the fact that the U. 
S. Government is using 8-in. shells of monel-metal steel 
and find that they pierce armor-plate equally as well as 
nickel-steel of the same percentage alloy. 

The most interesting evidence given before the Nickel 
Commission with regard to the possibility of making 
nickel-copper steel directly from the Sudbury ores was 
that of G. M. Colvocoresses, general manager for the Con- 
solidated Arizona Smelting Co., who owns a patent for 
manufacture of nickel-copper steel from nickeliferous 
pyrrhotite. Mr. Colvocoresses proposes to roast the ore 
in a "Wedge or other mechanical furnace to 0.5% sulphur 
and then either nodulize it and smelt in a blast-furnace, 
like an ordinary iron ore, with coke and limestone, or 
smelt directly in an electric furnace. By whichever 
method the pig is obtained, Mr. Colvocoresses advises re- 
fining in an electric furnace. Mr. Stansfield, on the 
other hand, suggests as a cheaper method, nodulizing the 
roasted ore, smelting in a blast-Turnace, bessemerizing 
the pig, and removing the last traces of sulphur in an 
electric furnace. 

As the cost of producing the alloy, Mr. Colvocoresses 
offers the following figures : Mining $2.50, crushing and 
roasting 50c, sintering and transportation $1. So the 



roasted and sintered ore would cost $4, or $8 per ton of 
pig. Coke $2.25, lime 30c, electrodes 60c, electricity 
$7, labor $3, making a total of $21.15 per ton of pig, and 
allowing 2008 lb. of pig to the ton of steel, comes to 
$21.25. To tfcis must be added burnt lime 30c, iron ore 
20c, ferro-alloy and manganese 50c, electrodes 68c, 
electricity $1.15, and labor $3.80, bringing the total cost 
to $27.88 per ton of refined steel, allowing $2.12 for sell- 
ing cost. This gives nickel-copper steel at $30 per ton. 
The weak point in these figures seems to be that two tons 
of roasted ore should equal a ton of pig. Assuming 40% 
iron for the ore, which is what is generally allowed, the 
roasted ore would not be expected to contain more than 
45% iron. This, however, would only make a difference 
of a dollar in the cost on the figures given. The value 
of the sulphur has not been taken into consideration be- 
cause the cost of transporting sulphuric acid from Sud- 
bury is prohibitive. In the light of more recent research, 
however, the possibility of producing elemental sulphur 
by the Hall or thiogen process should be attractive. 

Slush Castings 

When a metal or carbon mold is filled with a metal or 
alloy of low melting-point and the latter, after standing 
a brief interval, is poured out of the mold again, a shell 
is left in the mold that takes its form and constitutes a 
hollow casting possessing a better proportioned wall- 
thickness than it is possible to get with cores. Such 
castings usually take the form of more or less artistic 
articles, such as statuettes for clocks, and lamp bases. 
The metal is generally zinc, and the metal parts made 
in this way are known as slush castings. It has been 
found that the purer the zinc used, the better the cast- 
ings and the less trouble experienced from cracking. It 
is common to add a small amount of aluminum to the 
zinc, as it clears the surface of the metal and makes it 
run better. About 0.10% or less of aluminum is used, 
but it is a remarkable fact that, while 2 or 3% of alu- 
minum will cause the zinc to become stiff and slushy, 
with 5% aluminum the zinc pours well and produces 
good castings. Since aluminum increases the cost of the 
zinc, it is generally used as a de-oxidizer for making 
slush castings, and not for producing an alloy, and the 
amount added is less than 0.10%. Some manufacturers 
have found that the addition of not to exceed 0.005% 
of aluminum increases the fluidity of the zinc and per- 
mits slush castings to be made that are free from cold- 
shuts and cracks. This small amount of aluminum is 
most conveniently added in the form of a mixing-alloy of 
zinc and aluminum. — Daily Metal Reporter.

Welding Nickel Anodes 

In these days of attempts at conservation of every pos- 
sible waste material, any scheme with this end in view 
merits attention. It had been the custom to throw away 
small pieces of nickel anodes from plating-baths, but now 
the practice of utilizing every pound of nickel anodes for 
service by welding the scraps together has resulted in 
saving considerable money at many plating establish- 
ments. Until recent years it was usual to sell worn 




WELDING SCBAP NICKEL ANODES 

anodes as scrap for want of a thoroughly satisfactory 
method of utilizing them, and this was a source of con- 
siderable loss to the platers, for the junk-value of such 
material is less than one-half the original cost of the 
anodes. By welding the scraps together every pound of 
the costly metal is utilized for plating at a trifling cost 
for welding. The practice of welding such anodes is as 
follows : The worn anodes, as they are withdrawn from 
the tanks, are turned over to some workman who does 
the welding. A scrap of suitable size and shape is se- 
lected as a hanger, and other scraps are tacked to it by 
welding until the desired size and weight are secured. 
The tacking consists of melting the scraps, at the point 
of welding, by the heat of the oxy-acetylene flame, allow- 



ing t Ih-iii to lose into one piece. The tacking of a joint 

requires bul a i aent, as the temperature of the oxy- 

acetj lene urn . which is approximately 6300°F., causes 
the i < i < ■ i .- 1 1 to fuse quickly. No flux is used. Where 
necessary another piece of scrap nickel is use, I as a 
Slling-rod. The same flame is also used to remove the 
brass hooks from the scraps, the solder melting rapidly, 
leaving the pure anode to be welded. 

Several other methods of utilizing scrap-anodes have 
been tried in the past, but with uncertain results. The 
method of fastening them together by means of rivets 
and similar means are seldom dependable be- 
cause of uncertain conductivity. It is im- 
practicable for anyone but the manufacturer 
to re-melt and re-pour anodes, because in so 
doing the composition is changed. A decided 
advantage in welding the scraps together is 
that the original composition is not changed, 
and the fused joints insure conductivity equal 
to that of new anodes. Another advantage is 
the fact that no skill or experience in the art 
of welding is required to weld scrap-nickel 
anodes. Any workman of average intelligence 
can do it without previous knowledge of the 
process. The welding apparatus required is 
inexpensive. The illustration shows the weld- 
ing of scrap anodes by the Prest-O-Lite proc- 
ess of oxy-acetylene welding. Welded anodes 
are seen in the foreground. 



Silver- Coinage Ratio 

The United States ratio in dollar coinage is 
15.988, which brings the gold coinage value of 
an ounce of fine silver to $1.2929. Coinage of 
dollars has been discontinued since 1904. The 
weight of our subsidiary coinage, that is, half 
dollars, quarters, and dimes, is about 6.46% 
less in proportion to the silver dollar. As the 
fineness of the coins is the same, the seignior- 
age is correspondingly larger. Most other na- 
tions follow the same course. The Latin 
Union, comprising France, Italy, Switzerland, 
Belgium, and Greece, and those that have 
adopted the same system in whole or in part, 
namely Spain, Rumania, Bulgaria, Servia, Russia, and 
Finland, have as a unit a silver coin on the basis of 1 to 
15-J-, a ratio equal to a gold-coinage value of $1.3336 per 
ounce of fine silver. The subsidiary silver of these 
countries is coined on the still smaller ratio of 1 to 
14.38, equal to $1,438 per fine ounce of silver. Eng- 
land's coinage is all on the ratio of 1 to 14.288; that of 
the German empire on 1 to 13.95. The Scandinavian 
countries have a monetary union, and their silver coins 
are minted on a ratio of 1 to 14.78, and Holland's sil- 
ver coinage is all on a 1 to 15.63 basis. As far as Eu- 
ropean countries are concerned, it will be seen that the 
price of the white metal will stand a much higher valua- 
tion before coinage would have to be curtailed.

Chrome Brick in Copper Reverberatory Furnace 



By FRANCIS R. PAYNE 



•Several years ago one of the large Eastern copper 
refineries decided to utilize basic in place of silicious 
material in the walls of reverberatory furnaces for the 
treatment of foul blister copper, as the latter rapidly 
corroded the silicious linings. It was expected that 
there would be less slag formation, with a consequent 
decrease in the cost of treatment and a reduction in the 
metal losses. Magnesite-brick was first used, but while 
the corrosive action of the foul material was greatly re- 
duced, and the amount of slag formed was much less, 
the magnesite proved to be unsatisfactory in parts of 
the furnace because of its tendency to crack and spall 
when subjected to alternate heating and cooling. It was 
decided to substitute chrome-briek in the parts of the 
furnace that were affected. The results, as far as the 
reverberatory furnace was concerned, were satisfactory. 
The corrosion was small and the amount of slag formed 
was no greater than when using magnesite, and the ten- 
dency shown to crack and spall was eliminated. Gradu- 
ally the use of chrome-brick was extended to furnaces 
treating blister copper as well as those melting cathodes, 
and the results were so satisfactory that the silicious 
roofs were replaced by roofs of chrome-brick except 
where experience showed a more satisfactory perform- 
ance on the part of the silica-brick. It was immediately 
recognized, both for the magnesite and chrome-brick, that 
the absorption of metal was heavy, but it was felt that the 
longer life of the furnaces and the decreased cost of slag 
treatment and metal losses would more than offset the 
disadvantage. 

When repairs had to be made, the resulting 'cobbing' 
was sent to the blast-furnaces for the recovery of the 
copper, silver, and gold. It was, of course, realized that 
chrome was a neutral material and could not be fluxed, 
but it was thought that, at the blast-furnace tempera- 
ture, the cobbing would be melted, releasing the absorbed 
metals and causing the chromium oxide to pass out 
mixed with the blast-furnace slag. For a time this 
method appeared to be satisfactory, but as more of the 
cobbing was made and treated in the blast-furnaces, 
trouble developed. The capacity of the settlers began 
to be seriously reduced and slag-losses increased, due to 
improper settling. It was found that there had formed 
in the settler, between the matte and the regular slag, a 
layer of thick mushy slag. Thi6 could not be fluxed, 
could not be tapped out with the matte, and would not 
of itself overflow through the slag-spout. The only way 
to remove it without shutting down and digging it out, 
was to insert a pipe into the layer and, by use of com- 
pressed air, cause it to mix and overflow with the regular 

♦Abstract: Bull. A. I. M. E. 



slag. While this procedure cleaned the settler, it also 
resulted in metal-losses that could not be tolerated. 
Samples of this mushy slag showed it to contain as high 
as 25% chromium oxide, indicating that the cause was 
in the chrome-cobbing added to the charge. On discon- 
tinuing the treatment of the cobbing, the trouble dis- 
appeared. The result was to accumulate a considerable 
stock of chrome-cobbing, and experiments were under- 
taken to devise a satisfactory process for the removal of 
the metals so as to leave a residue that could be sent to 
the dump. 

The cobbing was crushed fine, thereby releasing the 
larger metallic particles, and treated in a reverberatory 
furnace with roasted pyritic ore and silica. This gave a 
fairly fluid slag in which the chromium was apparently 
soluble. A considerable amount of the metal was thus 
recovered, but the slag was still too rich in copper to 
throw away, and when sent to the blast-furnaces, in- 
duced a return of the former troubles in the settler. 
Fine crushing and fusion with a low-grade matte was 
expected to remove the metals and leave a slag suffi- 
ciently low in copper to be discarded. The results were 
unsatisfactory, for although the matte absorbed much 
of the metal, yet the slag was thick and pasty and con- 
tained considerable copper. It was believed that crush- 
ing, followed by mechanical concentration, might sep- 
arate the metal from the brick. Accordingly, the ma- 
terial was crushed and screened to remove the coarse 
metallics, and was then treated on a Wilfley table. Sizing 
resulted, but little concentration took place. The entire 
structure of the brick proved to be saturated with finely 
divided copper and copper oxide. Flotation was also 
tried without success, as the concentrate was too rich in 
chromium and there was too much metal in the residue. 
The most satisfactory solution yet found for the disposal 
of this material is to grind it, thereby freeing the larger 
metallic particles, and utilize the fine material in the 
manufacture of refractory brick, thus using the cobbing 
over and over again. Some slagging occurs, of course, 
and a certain amount of chromium goes to the blast-fur- 
nace, where the mushy slag is formed, but in small 
amounts it is easily taken care of, and eventually the 
accumulated stock is 'worn out' and sent to the dump. 

This experience suggests that chrome-brick is not very 
desirable for this class of work, and that magnesite 
should be used if possible. Experiments indicate that 
the tendency of the magnesite to crack and spall can be 
overcome by subjecting the brick to pressure before 
burning, which should also cause less absorption of metal. 
There is also no difficulty in treating the cobbing in the 
blast-furnace.

Colorado Metal Production in 1917 



The mine output of gold, silver, copper, lead, and zinc 
in Colorado for 11 months of li'lT. and the estimated 
output for December, according to data compiled by 
Charles W. Henderson, of the U. S. Geological Survey, 
amount to about $16,020,000 in gold, 7,327,000 oz. silver, 
67,500,000 lb. recoverable lead, 8,700,000 lb. copper, and 
114,000,000 lb. recoverable zinc, having a total value of 
nearly $40,600,000, compared with $19,153,821 in gold. 
7,656.544 oz. silver, 70,914,087 lb. lead, 8,624,081 lb. 
copper, and 134,285,463 lb. zinc, having a total value of 
#49,200,675 in 1916. 

The lead smelters at Globe, Leadville, Pueblo, Durango, 
and Salida were operated about as in 1916, the ore 
coming from Arizona, Canada, Colorado, Idaho, South 



Keokuk, Iowa. The "Western ziue-oxide plant at Lead- 
ville was operated steadily mi zinc-carbonate ores. Cop- 
per ore and cyanide precipitates were shipped Erom Colo- 
rado to the smelter at Omaha, Nebraska, and some cop- 
per and lead ores were shipped to plants in Utah. 

As predicted in the six months' review of operations, 
the production from Cripple Creek was less than in 1916, 
but the production during the last six months of 1917 
was somewhat larger than during the first six months,

The flotation plant installed in 1916 at the Durango 
smelter to remove the zinc from the zinc-lead sulphide 
ores of the San Juan region continued to be operated 
during 1917. The copper-matting plants at Ouray and 
Vulcan were idle. The United States Zinc Co.'s mag- 
netic wet-concentration mill and zinc smelter at Pueblo 
were actively operated on zinc ores from Colorado and 
other Western States. The Western Chemical Co. 's acid 
plant and magnetic-separation wet-concentration mill at 
Denver and the Empire Zinc Co.'s 200-ton magnetie-

both treating chiefly Leadville lead-zinc sulphide ores.

continued to treat zinc-lead-copper sulphide ores from 
several counties in Colorado, part of the product being 
forwarded to this company's electrolytic zinc plant at 



and the total production of Cripple Creek for the year 
was $10,549,000, a decrease of $1,570,000. During the 
year the Roosevelt adit was continued so as to end at 
the Portland mine, not at the Golden Cycle-Vindicator 
mine, as originally intended. A cross-cut was also 
started toward the Cresson mine. The Portland com- 
pany abandoned its plan of using the flotation process 
in its Independence mill and continued to use the cya- 
nide process with considerably increased capacity. The 
Vindicator company continued its experiments with the 
flotation process. The Golden Cycle eyanidation mill, at 
Colorado City, and the Portland eyanidation mill, at 
Colorado Springs and Victor, were operated steadily. 
The yield from the small cyanide plants of the Cripple 
Creek district was not so large as usual and the ship-

siderably.

ing quantities from the Downtown district, unwatered in 
1916. Some zinc-carbonate and zinc-sulphide ores were 
shipped from the Fryer Hill district, also unwatered in 
1916, and considerable iron-sulphide ores were shipped 
from the unwatered Carbonate Hill district. The output 
of zinc carbonate from the Leadville district decreased 
heavily. The output of zinc carbonate was 68,500 tons 
of 19.6%, as compared with 85,513 tons of 21.52% in 
1916. The zinc-sulphide smelting and concentrating ore 
was 130,000 tons of 21.7%, against 147,295 tons of 
20.96% in 1916. The Derry Ranch dredge, below Malta, 
continued operations during the year. 

The San Juan region of Dolores, La Plata, Ouray, San

San Miguel county mills maintained their production of 
gold, which was about $2,000,000, and increased their 
production of silver to over 1,000,000 oz., but consider- 
able quantities of the ore treated in these mills came from 
operations in Ouray county along the strike of the veins. 
San Juan county produced considerably less gold but 
made an appreciable increase in the output of silver and 
a large increase in the output of lead, copper, and zinc. 
The yield of zinc in Dolores county increased heavily, 
but the yield of the other metals fell off somewhat. In 
Ouray county there was naturally a heavy decrease in 
the output of gold, due to the idleness of the Camp Bird 
mill, both the mine and mill having been closed-down in 
August 1916 to await the completion of the low-level 
adit, which was driven steadily during 1917. This adit 
is to be 10,700 ft. long and will cut the Camp Bird 450 
ft. below the present deepest workings and 800 ft. below 
workings of the next most important section. 

Boulder, Gilpin, and Clear Creek counties produced 
$808,000 in gold, 956,000 oz. silver, 1,240,000 lb. cop- 
per, 6,336,000 lb. lead, and 3,300,000 lb. zinc, as compared 
with $1,001,489 in gold, 881,518 oz. silver, 1,243,756 lb. 
copper, 5,681,392 lb. lead, and 2,572,575 lb. zinc in 1916. 
Boulder county produced $50,000 'less gold and 12,000 oz. 
less silver, also less copper and lead. Clear Creek county 
increased its output of silver, lead, copper, and zinc, but 
decreased considerably its output of gold. The produc- 
tion of gold in Gilpin county fell off approximately 
$100,000, but there was an increase in the output of 



lead, and for the first time in years there was an output 
of zinc. 

In Chaffee county the output of gold, lead, copper, and 
zinc fell off, but the output of silver increased. The 
output of Pitkin county (Aspen) was 649,000 oz. silver 
and 13,633,000 lb. lead, an increase of 71,000 oz. silver, 
but a decrease of nearly 4,000,000 lb. lead. The output of 
zinc from this county, however, increased approximately 
300,000 pounds. 

The production of Creede (Mineral county) fell off 
considerably, as did that of Gunnison county. Summit 
county produced $623,000 in gold, 157,000 oz. silver, 
620,000' lb. lead, 30,000 lb. copper, and 19,000,000 lb. 
zinc, as compared with $673,891 in gold, 120,207 oz. 
silver, 14,581 lb. copper, 1,688,637 lb. lead, and 13,940,- 
948 lb. zinc in 1916. The four gold dredges at Brecken- 
ridge produced about the same output as in 1916, but the 
output of pocket gold was not equal to that of 1916. 
During the later part of the year a new dredge was 
launched in this district. There was very little activity 
at Montezuma, but several properties continued to work 
at Kokomo. 

Mining was active at Red Cliff, Eagle county, though 
the yield of zinc was somewhat less than in 1916. Some 
shipments were made from the Brush Creek district. 
The output from both lode and placer mines in Park 
county decreased. The output from the mines of Custer 
county was the largest for several years, and there was 
also a considerably increased production from the Kerber 
Creek district of Saguache county. 

The largest output of ground barytes is made by three 
Missouri companies. The establishment of a grinding- 
plant at Cartersville, Georgia, by Thompson-Weinman 
& Co. will do much toward increasing the production of 
Georgia and Alabama mines, as it will give a ready out- 
let for small lots of barytes mined from various deposits. 
It is reported that a company is contemplating the grind- 
ing of barytes at a plant near Los Angeles, California, 
now used for other purposes. Such a step might be wel- 
comed by the Pacific Coast makers of mixed paints, who 
now obtain their ground barytes in the East and pay 
high freight-rates to the coast. White bleached and 
floated ground barytes is used in ready-mixed paints, in 
the rubber industry, and in making stiff heavy card- 
boards and papers. Off-color ground barytes is used in 
preparing colored mixed paints and in various chemical 
industries. There is at present a fair demand for do- 
mestic barytes. Quotations on prime white or floated 
material range from $30 to $36 per ton, and for off-color 
from $22 to $24. The output is increasing, but is re- 
tarded by shortage of labor and difficulties of transporta- 
tion. 

Taxing net earnings of mines alone, says Lewis E. 
Young, fails to reach the non-producing mine which yet 
may possess some value; also valuation based on net 
earnings may not take a proportionate share of revenue 
from mines.

MAMMOTH, UTAH 

May Day. — Tintic Bonanza. — Tintic Standard. — Eaole & Blue 
Bell. — Tintic Milling. — Dragon Con. 

Owing to the holidays the metal output of the Tintic district 
was materially reduced during the week ended December 29, 
being almost 50% below normal. The shipments were as fol- 
lows: Dragon, 26 cars; Chief Consolidated, 14; Eagle & Blue 
Bell, 14; Tintic Standard, 10; Centennial Eureka, 9; Iron 
Blossom, S; Colorado, 6; Mammoth, 6; Grand Central, 5; Gold 
Chain, 5; Victoria, 4; Chief Con. manganese lease, 3; Empire 
mines, 2; Scranton, 2; Minnie Moore, 1; Golden Key, 1; 

Victor Con. 1; Yankee, 1; making a total of 118 cars. While 

the past year has been an uneventful one for the May Day, 
the work which is now being done on the 700-ft. level to the 
east of the shaft is promising. Already some small bunches of 
ore have been found and it is hoped that a continuation of 

this work will result in the discovery of another orebody. 

At a meeting which was held recently at Salt Lake City it was 
decided to turn over the stock of the Tintic Bonanza Mines 
Co. in exchange for shares of the Eureka Standard Con. M. Co. 
on a basis of 100 shares of Eureka Standard for 127 shares of 

stock in the Tintic Bonanza. Today the Tintic Standard is 

one of the biggest mines in the district; there are thousands 
of tons of ore in sight and the company has a large tract of 
undeveloped ground, owning one of the largest tracts of min- 
eral land in Tintic. A recent strike has been made a short 
distance to the north of the new shaft, where a large body of 
ore averages 70 oz. silver, $5 to $6 in gold, 10 to 12% lead, and 
from 2 to 3% copper. The main ore-channel has now been 

opened for 500 or 600 ft. A report was received from D. E. 

McPherson, the superintendent of the Deseret Mountain prop- 
erty, that the station on the 300-ft. level of the new shaft had 
been completed and the work of sinking had been resumed. 
When the 300-ft. level was reached a cross-cut was run into the 
vein, which proved to be 30 ft. wide. The vein was 6 ft. wide 
at the surface. Two drifts have been run north and south on 
the vein from the cross-cut. The shaft will be sunk to the 

500-ft. level as fast as possible. The Plutus property is being 

developed at three different points. A drift is being driven 
from the Victoria shaft into the Plutus ground, another drift 
is being run from the Chief Consolidated workings, and a 
force of men is at work in the shaft. The shaft is down 400 
ft., where a drift had been started to the south. At the time 
the Plutus was taken over by the Chief company the stock 

was selling at 14c, now it is up to 35c. Eagle & Blue Bell 

Mining Co. is one of the district's heaviest producers, but has 
suffered more than any other mine on account of embargoes 
that smelting companies have placed on ore. The Eagle 
shipped a total of 625 carloads of ore, and it is estimated by 
the company's officials that this is not half the amount that 
the mine is capable of producing. The mine is equipped with 
gear capable of hoisting 300 tons per day, but at times during 
the past year it has almost been necessary to suspend oper- 
ations because the embargo prevented the mine from shipping. 

Iron Blossom Mining Co., controlled by Jesse Knight and 

associates of Provo, is the third largest producer in this dis- 
trict. During the past year this mine has sent out 1201 car- 
loads of ore, and has paid regular quarterly dividends of 5c. 



per share. The principal constituent of the ore is copper, al- 
though lead, silver, and gold are also present. Tintic Mill- 
ing Co. was organized over two years ago, and for several 
months has been operating a custom-mill at Silver City to treat 
the low-grade ores that cannot be shipped to the smelters. 
The plant has proved a successful enterprise, and is treating 
nearly 300 tons of ore daily. Five cars of precipitate have 
been shipped to the smelters, and four or five carloads of 
bullion have been marketed. The Centennial Eureka Min- 
ing Co., known in this district as the Blue Rock, was pur- 
chased several years ago by the United States Smelting Co., 
and since has paid millions of dollars in dividends. For many 

years it was the heaviest producer in the district. The 

Tintic Delaware is a new company organized to develop the 
Ekker group of 14 claims in the West Tintic mining district. 
Enough ore to load a couple of cars is already on the dump 
awaiting shipment, and the management intends to commence 

shipping shortly. Mammoth mine is one of the oldest and 

heaviest producers of the camp. It is owned by Samuel Mc- 
Intyre of Salt Lake City and during the year has sent out 

739 carloads of good-grade ore. The Dragon Consolidated 

Mining Co. is another company controlled by Jesse Knight and 
associates, and is one of the oldest mines in the district, having 
been a producer for more than 40 years. This year the mine 
leads the list of shippers, having produced 1774 carloads. An 
average of 34 carloads per week has been sent out, some of the 
low-grade ore going to the Tintic milling plant and thousands 
of tons of iron ore to the different smelting companies of the 
State for fluxing. The Dragon also is sending out considerable 
ore of a higher grade, which has enabled it this year to pay 

dividends for the first time in many years. The Eureka 

King Mining Co. is a North Tintic property in the vicinity of 
the Lehi Tintic. Development work has been pushed during 
the past few months, and at present consists of a shaft which 
is down 350 ft. The property is owned by Salt Lake people. 

George Chiulos is managing the work there. The Copper 

Leaf Mining Co. is a new company situated in the extreme 
eastern end of the district adjoining the Tintic Standard. The 

shaft is down 400 ft. The North Beck Mining Co. shaft is 

nearing the 300-ft. level, and sinking is going along as rapidly 
as three shifts can handle the work. The Gemini has ship- 
ped 457 carloads of ore during the past eleven months. This 
mine is controlled by Jackson McCrystal of Salt Lake City. 
The orebody on the 1600-ft. level is one of the biggest that has 
been found in this mine. 

TONOPAH, NEVADA 

Tonopah Mining. — Tonopah Extension. — Tonopah Belmont. — 
West End Con. — Jim Butler. 

The Tonopah Mining Co. shipped 25 bars of bullion valued at 
$46,750. The 50th dividend amounting to 7*c. per share has 
been declared and is payable January 21. The total dividends 
to date total $14,275,000. At the Silver Top 35 ft. of develop- 
ment has been done, 17 ft. at the Mizpah, and 44 ft. at the 
Sandgrass. During the past week 2450 tons of ore was milled, 
averaging $13 per ton. Last week's production was 1950 tons. 

The Tonopah Extension Mining Co. milled 9219 tons of 

ore during November, resulting in a net profit of $11,719. At

the No. 2 shaft 133 ft. of development has been done and 170 
ft. at the Victor. At the No. 2 on the 850-ft. level stoping con- 
tinues on a 4-ft. face on the Murray vein. At the 1260-ft. 
level the Merger vein is being worked on a 4-ft. face and the 
O. K. vein on a 3-ft. face. East and west drifts from cross-cut 
510 on the 1350-ft. level are unchanged. Raise No. 567 shows 
a 6-ft. face of ore. On the 1540-ft. level of the Victor raise No. 
1503 made a connection with the level above. Low-grade ore 
was exposed by the raise. Work in the 1501 winze has been 
discontinued, pending the erection of an air-hoist. The face 
of the winze is still in ore. On the 1680-ft. level 1600 south 
cross-cut was extended 60 ft. The 1600 west drift advanced 
32 ft. on a 7-ft. face of good ore. The face of the west drift 
is about 270 ft. from the west line, where the Cash Boy Con- 
solidated Mining Co. has worked the vein at approximately 
the same level. Work in the east drift 1600 has been resumed, 
and shows a 3-ft. face of ore. The production the past week 

was 2380 tons. The Tonopah Belmont Development Co. 

milled 10,310 tons of ore during November, resulting in a net 
profit of $66,224. On the 800-ft. level the east drift from the 
south-east cross-cut No. 8013 shows a 3-ft. face of excellent 
ore, while the west drift shows 5 ft. of ore on the South vein. 
Raise No. 18 continues to advance on a 5-ft. face of ore on the 
South vein. On the 1000-ft. level raise No. 73 made a connec- 
tion proving a fair body of ore. Last week's production was 

2147 tons. At the Ohio shaft of the West End Consolidated 

Mining Co. drift No. 535 continues in a full face of fair ore. 
Drift No. 536 made a connection with drift No. 531, proving 
an excellent body of ore along the strike of the vein. Winze 
No. 534 is in good ore. On the 555-ft. level drift No. 1 con- 
tinues in a full face of ore. Raise No. 814 continues in a 
silicifled zone. The stopes at the West End shaft show higher 

average grade. The output the past week was 959 tons. 

The MacNamara Mining Co. cut the Ohio vein in a raise from 
the west cross-cut on the 700-ft. level. The vein is wide and 
of fair grade where it was cut by the raise. The production 
the past week was 512 tons. The Jim Butler Tonopah Min- 
ing Co. milled 2916 tons of ore during November, resulting in 
a net profit of $7143. Work has been suspended in the west 
cross-cut on the intermediate below the 500-ft. level and a 
raise started to cut the vein above. Raise No. 653 from the 
intermediate continues on a 4-ft. face of ore. The production 

during the past week was 559 tons. On the 1000-ft. level of 

the North Star on a 2-ft. face of excellent ore a raise is being 
put up. An intermediate from the raise No. 1050 is being 
driven on a 2-ft. stringer of ore. A shipment of 56 tons was 

made last week. The Montana produced 77 tons, the Rescue 

6S tons, and miscellaneous 7 tons, making the week's produc- 
tion at Tonopah 8715 tons with a gross value of $152,513. 

MAYER, ARIZONA 

General Development Co. — Arizona Binghampton. — Copper 
Queen. — Consolidated Arizona. 

Announcement has been made by directors of the Jerome 
Copper Co. that ore has been found in the 930-ft. adit in the 
South Jerome district which was taken over last summer by 
the General Development Co. It is considered to be one of 
the most important strikes of ore made during the past year. 
The vein is about 30 ft. wide, and is a milling-grade of copper- 
silver ore. Drifts have been started each way on the vein and 
cross-cutting is in progress, with ore still in the face. J. G. 
Flinn, the mine superintendent, states that the mine indica- 
tions could not be better. This strike is of importance to the 
district because it is the first property to be taken over in he 
Jerome-Phoenix mineralized belt by this strong Eastern com- 
pany, and the success of the first attempt will stimulate the 
company to further development on other properties in the 
district. The company owns the Christmas mine, three miles 
east of Mayer, which was the first one acquired last summer. 



The Christmas mine is right in line with the Arizona Bing- 
hampton and Copper Queen mines on the south extension, 
with only a few claims between. There are places opened up 
that will run better than 20% copper. The discovery at the 
Jerome mine is especially gratifying to E. A. Kastner and 
Homer King, of Prescott, who were instrumental in interest- 
ing the General Development Co. in this district. The 

Arizona Binghampton company has begun to sink the 600-ft. 
shaft to the 1200-ft. level. The new shaft is to be three-com- 
partment and there will be a station cut at the 700 or 800-ft. 
levels. The sinking of this shaft will be watched with great 
interest for it will determine what may be expected with depth 
in the Yavapai schist. The main orebody on the 600-ft. level 
is 51 ft. wide and it is all a milling-grade of copper ore. This 
same orebody has come down through the several levels above, 

getting wider and better in grade with depth. Over the 

divide from the ABC mine, the Copper Queen company has 
discovered new ore in a raise from the bottom of the 300-ft. 
winze. The ore-shoot has widened to seven feet and runs 5 
to 6% copper. The development work is now being confined 
to the winze level. There are a number of promising out- 
crops on the surface that have not as yet been prospected. 

While no public announcement has been made by the Consoli- 
dated Arizona Co. as to the success- of the new work on the 
1200-ft. level in the Blue Bell mine, it is commonly reported 
that some ore has been found in the drift to the north that 
runs higher in gold and about the same in copper as the big 
orebodies on the 1000-ft. level. On the 1000-ft. level there are 
stopes 40 ft. wide of milling and smelting grades, and now on 
the 1200-ft. level the ore found is proving richer. Recent de- 
velopment at the extreme south end of the Blue Bell mine, 
about 2000 ft. south of the main shaft, has opened an orebody 
better than 25 ft. wide at a depth of 75 ft. The company plans 
to run a drift on the 800-ft. level southward to open the new 

strike at depth. The new strike in the Pocahontas mine is 

continuing to grow better every day. The vein is about 12 
ft. wide with portions running into high-grade shipping-ore. 
Some of the machinery has arrived for the new flotation mill. 
Another promising strike of silver-lead-gold ore has been 
made in the Black Diamond mine, near Walker, the control 
of which is owned by J. Irwin, of Prescott. The ore, which 
covers the bottom of the shaft, runs from $50 to $S0 per ton in 
gold, silver, lead, and copper. 

COBALT, ONTARIO 

Silver Production. — Temiskaming. — McKinley-Darraoh. 

The year just ended has been a profitable one for the mines 
of Cobalt. Of the $16,000,000 produced during the year approxi- 
mately $8,600,000 is net profit. Of the latter amount about 
$5,500,000 has been disbursed in dividends, and the balance 
employed in new ventures farther north in the endeavor to 
acquire new mining property. During the year the price of 
silver has averaged about 81.7c. per ounce, which compares 
with 65.6c. in 1916 and 49.7c. in 1915. The current year's in- 
crease above that of 1915 just about makes the difference 
between profit and loss. During last week the Mining Cor- 
poration and the Nipissing company shipped bullion valued at 
approximately $200,000. In addition to sending out large ship- 
ments of ore, the Mining Corporation has shipped 4,051,966 
oz. during the current year. The output from the Nipissing is 
second only to that of the Mining Corporation; Kerr Lake 
ranks next. 

The O'Brien mine is maintaining a large silver production, 
the output for the current year being about 100,000 oz. per 
month; the Miller Lake O'Brien, at Gowganda, is yielding 

about 84,000 oz. per month. At the lower levels of the, 

McKinley-Darragh a large tonnage of low-grade ore is being 
opened up, and some high-grade is also found. The physical 
condition of the mine is good. The Chambers Ferland has 



January 12, 1918 



MINING and Scientific PRESS

found some patches of high-grade ore Just above the contact, 
and here too, considerable low-grade Is being broken. The 
exploration at depth is now well under way and quite an ex- 
tensive portion of the property heretofore unexplored Is in 
line for early development. 

The oil-flotation plant at the McKinley-Darragh has been 
closed down for the winter and will be reopened in the earl; 
spring. The plant was only completed during the past few 
weeks, and was kept in operation just long enough to prove it 
to be satisfactory. However, the economic treatment of the 
sand from the bed of Cobalt lake could not be carried on dur- 
ing the cold weather. Underground operations at the Mc- 
Kinley-Darragh are of a favorable nature. 



TORONTO, ONTARIO 

Canadian Metal Output. — Groch Flotation Machine. — Mc- 
I ntt re. — Schumacher. — Coniagas. 

The Canadian Department of Mines estimates the value of 
the total mineral production of Canada during 1917 at approxi- 
mately $200,000,000, as compared with $177,281,534 in 1916. 
The output of nickel, lead, zinc, pig-iron, and steel showed a 
considerable increase, while there was a decline in the pro- 
duction of gold, silver, and copper. The principal metallic 
items were, gold $17,000,000, silver 23,500,000 oz., copper 113,- 
000,000 lb., nickel S4,800,000 lb., lead 56,700,000 lb., zinc 31,- 
000,000 lb., pig-iron 1,1S6,000 tons, and steel ingots and direct 
steel castings, 1,735,000 tons. Coal was produced to the amount 
of about 14,100,000 tons. The seriousness of the coal situa- 
tion, which is causing much hardship and loss at many points 
in eastern Canada, again is directing attention to the extensive 
peat deposits that might furnish a source of fuel to take the 
place of the uncertain supply of imported coal. Attempts have 
been made from time to time, under Government direction, 
to produce a peat fuel that could compete successfully with 
coal, but although a satisfactory fuel was produced the ex- 
periments proved commercial failures. Now, however, owing 
to the scarcity and steadily increasing price of coal, conditions 
have changed so radically that such a scheme would have far 
better prospects of success than when formerly attempted. 
Attention is being drawn to extensive peat bogs a few miles 
south of Cochrane in northern Ontario as a source of excellent 
raw material for peat-fuel manufacture. In October last a 
survey of these deposits was made by A. Anrep, an expert of 
the Canadian Mines Branch, who is in favor of the project, 
which is expected before long to take practical shape. 

The Groch centrifugal notation system is coming into favor 
and is being introduced for the treatment of other metals 
than silver. It has been for some time in successful operation 
for gold extraction at the Miller Independence mine, Boston 
Creek, and the Mclntyre of Porcupine is arranging to try a 
Groch machine for experimental work. The system is stated 
to he suited also for the treatment of molybdenite, graphite, 
and the recovery of copper from sulphide. A contract has 
been let for the installation of a flotation plant on a molyb- 
denite property near Amos, on the Transcontinental Railway. 
The Groch machine is a Canadian invention. 

The Mclntyre, which recently declared a 5% dividend, is at 
present the only dividend-paying mine in Porcupine. It is 
understood that current earnings are considerably in excess 
of the dividend requirements of 20% per annum. The ore- 
reserve has been increased considerably by underground opera- 
tions. A new hoist has been erected with a capacity for 
operating to a depth of 2000 ft. Some delay was occasioned by 
water in sinking the shaft on the Jupiter property, but new 
pumping equipment has overcome the difficulty and the shaft 

has now nearly reached the 1000-ft. level. The Schumacher 

has improved its position lately. Its main workings have been 
carried to the 600-ft. level and, despite labor shortage, the mill 



has been kept operating t" capacity. Following the example 
of other successful mines, deep mining will be undertaken and 

the shaft put down to the 1000-ft. level. The Davidson has 

received all of Its mill machinery and It Is expected that the 
mill will be ready for operation In about a month. There is 
$80,000 worth of ore on the dump and enough blocked out 
underground to keep the mill In operation for two years. The 
West Dome Consolidated has made arrangements to have Its 
ore treated at the Dome Lake mill. It has 900 tons of $17 ore 
broken and ready to be hoisted and 6000 tons of ore, running 
$9 per ton, on the dump. The continuation of the main ore- 
body of the Porcupine Crown has been cut on the 1000-ft. level, 
where the ore compares favorably with that of the upper 
levels. 

The Coniagas, of Cobalt, is sinking a 3-compartment shaft 
on the Ankerite gold property which it acquired recently. 
Progress is being made at the rate of seven feet per day, which, 
it is claimed, establishes a new record for quick sinking in 
northern Ontario. At the annual meeting of the Coniagas 
Mines on December 31, it was announced that $500,000 had 
been paid in dividends during the year, bringing the total 
distribution to shareholders up to $8,740,000. The output of 
silver was 1,344,267 oz. as compared with about 1,750,000 the 
previous year. The directors of the Peterson Lake have de- 
cided to proceed as soon as possible with the erection of a mill 
for the treatment of slime on the Seneca Superior dump. An 
offer, made by the Beaver Consolidated to the Temiskaming of 
the right to purchase over 870,000 shares of the Kirkland Lake 
at 40c. per share, giving them an equal interest, was submitted 
to, and rejected by, the Temiskaming shareholders Decem- 
ber 28.

Last year the mines of the Leadville district reached their 
maximum output and set up a new record for gross value of 
production. The one dominant factor that made possible this 
remarkable success was manganese. With the exception of 
lead, all other metals registered a loss as compared with the 
totals of 1916. Lead showed a gain of 2,200,000 lb. in output

and an increase of over $250,000 in value. Gold fell off 20,500 
oz. with a loss of $500,000 in value. Silver, in spite of an 
increase in value over 1916 of 16c. per ounce, registered a 
loss in production of over 600,000 oz.; copper dropped over 
$87,000; and spelter nearly $2,000,000. To make up this total 
loss of nearly $3,000,000 and still show a gain of $1,750,000 
over 1916, manganese closed the year with an increase in ton- 
nage of 103,023 tons. In arriving at the gross value of the 
manganese output it was necessary to estimate as closely as 
possible the metal content of the ore and rate it at the highest 
market quotation. The total production of 185,391 tons of 
ore represents the wet product as extracted from the mines. 
Moisture was figured at 15% and reduced from the total, leav- 
ing 157,483 dry tons. The average manganese content of this 
ore, conservatively estimated, was 23%, giving 36,272 tons 
of metallic manganese. Eastern markets quote manganese at 
$1.20 per unit on a basis of 48%; and so $120 per ton was 
used in computing the gross value of the Leadville product. 
There is a great difference, however, in the price paid to the ore 
producers that offered the metal in Eastern markets. The 
highest contract now known to govern shipments from the 
Leadville mines calls for a price of $10.50 per ton for 30% 
ore f.o.b. Leadville. This particular ore is shipped to Penn- 
sylvania and is subjected to a freight charge of $14 per ton, 
making the total cost to the buyer $24.50. From $10.50, the 
price at the mine runs as low as $4.50, according to the grade 
of ore. Beginning as early as November of 1916, there was 
a marked increase in the development of manganese ores. 
The War brought a steadily growing demand for the metal; 
and, particularly after the bottoms used in the manganese trade 
with Spain and South America were being taken up by the 
Government for other service, the demand rapidly became 
acute. The market for the ore grew stronger, and with the 
increased price made a profitable outlet for low-grade material. 
In 1916 practically all of the Leadville manganese output, 
amounting to 80,000 tons per year, was shipped to the Colorado 
Fuel & Iron Works at Pueblo. The bulk of this tonnage was 
produced by the Star Consolidated Mining Co., which extracts 
an ore averaging 20% manganese. Some better-grade material 
was mined in the properties on Poverty Flats but the tonnage 

was small. Early in 1917, Eastern ore-buyers made their 

appearance in the Leadville district and awakened a new in- 
terest in manganese. Several large deposits of ore that would 
average 30% were soon uncovered, the most important dis- 
coveries being at the Nisi Prius in Iowa gulch; Bohen, Grey 
Eagle, Penrose, and Northern in the Down Town section; Fair- 
view on Poverty Flats; Lime and Bulls-eye on Iron hill; and 
Carbonate on Carbonate hill. These properties all became 
active producers in 1917 and shipped a heavy tonnage, much 
of the ore being sent to Eastern buyers, where better prices 
are secured than are offered at Pueblo. The future of man- 
ganese is regarded as bright so far as Leadville is concerned. 
The output for 191S is expected to double that of last year and 
higher prices are looked for coupled with a demand for a still 
lower-grade product. A number of new enterprises are now 
being started with the purpose of opening new manganese 
orebodies. 

Aside from the manganese properties, seven big companies 
stood out last year as the real backbone of the district. The 
Yak Mining, Milling & Tunnel Co., half of which was sold 
recently to the American Smelting & Refining Co., was the 
heaviest producer with a total of over 70,000 tons. The Wolf- 
tone shaft of the Western Mining Co., followed with approxi- 
mately 66,000 tons. The Ibex Mining Co. showed a total output 
of 50,000 tons: the Star Consolidated Mining Co., 60,000 tons; 
the Down Town Mines Co., 40,000; the Leadville Unit, 40,000; 
and the Iron Silver Mining Co., 40,000. Numerous smaller 
properties combined to make up the remainder of the total 
output. The work accomplished by Warren F. Page, man- 
ager for the Luema Mining Co., was the most important devel- 



opment undertaken in new territory during the year. A cross- 
cut from the 300-ft. level of the Valley shaft was carried 900 
ft. north under Prospect mountain and an immense deposit 
of low-grade sulphide ore was found in the white lime. A 
former adit driven from surface near the Valley shaft reached 
upper-contact ort 1700 ft. from the portal. The presence of the 
two main Leadville ore-zones under Prospect mountain is now 
determined. Another big adit to be driven from the Arkansas 
valley, east under the mountain, is planned for the coming 

spring. The re-opening of the old Mikado shaft on Iron 

hill by the Iron Silver Mining Co., and the discovery last year 
of immense bodies of rich lead-zinc-silver sulphide ores in the 
lower reaches of the property was an important event that 
promises to result in making this mine the biggest producer in 
the district. The sinking of the Mikado shaft from its present 
depth of 1135 ft. to 1500 ft. is to be undertaken at some future 

date to fully develop the ore deposits now uncovered. At 

the Wolftone shaft of the Western Mining Co., draining to the 
bottom level, 1250 ft., has resulted in the discovery of three 
huge bodies of sulphide ore. These have been found in the 
Wolftone, Mahala, and Maid of Erin claims, and rank with 
the biggest ore-shoots now open in the district. The sinking 
of the Wolftone shaft to greater depth is also to be under- 
taken. 

The Down Town Mines Co., operating through the Penrose 
shaft, has made a number of important discoveries. Large 
orebodies have been found on five levels ranging from 300 to 
900 ft. in depth. Iron, silver, manganese, lead, copper, and 
zinc are being produced. The company plans to re-open the 
old Coronado shaft for hoisting, as much of the ore now 

blocked out is in this property. The sale of one-half interest 

in the Yak to the A. S. & R. Co., and the transfer of the man- 
agement to the latter corporation is the biggest transaction of 
the past year. The price paid is stated to have been $500,000. 
Under the new control, vigorous and extensive development 
throughout the property is to be undertaken; and it is believed 
by some authorities that the old objective of the big bore, the 
piercing of Mosquito range and reaching of the rich gold veins 
of Park county, will be included in the campaign. 

Although not in the Leadville district proper, the recent dis- 
coveries of molybdenum at Climax, just over the line in Sum- 
mit county, are of the greatest importance. During the past 
year three strong corporations, the American Metal Co., Molyb- 
denum Products Co., and Pingrey Mines Co., entered the field, 
and the two first mentioned are new erecting milling plants 
and carrying on development in their holdings. The Pingrey 
company plans to begin work this spring. A satisfactory proc- 
ess of treatment has been perfected by each of these concerns, 
and it is believed that a large tonnage of ore will be concen- 
trated during the present year. The molybdenum deposit on 

Bartlett mountain near Climax was first discovered several 
years ago by Charles J. Senter, pioneer prospector of the Ten 
Mile, or Robinson, mining district, who has made repeated 
efforts to attract the interest of both American and foreign 
steel manufacturers to this remarkable deposit. These efforts 
failed to bear any fruit until 1915, after the War broke out. 
Then the value of molybdenum was demonstrated fully. Eng- 
land soon perfected a process for using molybdenum in steel 
and sought a supply of the metal. America was then aroused 
to the importance of uncovering large deposits of molybdenum, 
and a market for the metal was established. O. A. King, man- 
ager for the Pingrey Mines Co., was first to see the great pos- 
sibilities of the Bartlett mountain deposits. In 1915 he had a 
trial lot of 1000 tons of the ore extracted from his property at 
Climax and treated by flotation at the Leadville district mill. 

The results of this experiment were satisfactory, the 

finished product being sold for $35 per unit. At that time, 
however, there was no assurance for a continued market for 
the metal, but now it is possible to make long-term contracts 
for the product.

ALASKA 

(Special Correspondence.) — Contradictory to a previous re- 
port, it is learned on authority that the Willow Creek Mining 
Co. has not surrendered its lease on the Gold Bullion. It now 
has a force of men freighting supplies and it plans to drive 
two headings in the mine during the winter with a view to 

developing ore. Herschel Parker of New York reported 

finding platinum generally distributed in the gravels of 
streams heading in the Mt. McKinley region. It is not known 
if in commercial quantity, but the hope is entertained that the 
combined gold and platinum will make possible the successful 

exploitation of large areas of dredging ground. From near 

Seldovia, on Kenai peninsula, chromite ore carrying 50% 
chromic oxide was mined and shipped; deposits of chromite 
and magnetite were reported from near Snug Harbor. 

Anchorage, December 20. 

ARIZONA 

MARICOPA COUNTY 

(Special Correspondence.) — Messrs. Warnock and Holmes 
have taken a bond and lease on the Copper Belt property in 
the Harqua Hala mountains, 20 miles from Aguila. A road is 
being built to connect with the road now used for hauling 
manganese ore to Aguila when complete shipping will com- 
mence. The ore is said to run 20% copper and $12 gold. 

Phoenix, December 28. 

MOHAVE COUNTY 

(Special Correspondence.) — A low-level adit has been com- 
menced by the Arizona Butte Mines Co., to cross-cut and de- 
velop the many veins which are known to exist in Stockton 
hill; it will be driven on the Prince George vein. Consid- 
erable progress is being made in the mines of the Union Pass 

district. A two-stamp mill is being built at the Arabian 

property. A cross-cut on the 400-ft. level to cut the Sheep- 
tail vein is being driven at the Banner. The shaft on the 

Lucky Prince is nearing 200 ft. in depth. It is expected that 

diamond-drilling will commence within a few days at the 
Grand Island property. Two 1000-ft. holes are planned. 

Kingman, December 2S. 

YAVAPAI COUNTY 
(Special Correspondence.) — It is reported that a 6-ft. vein 
carrying lead, copper, and silver to the value of $100 per ton 

has been cut in the 200-ft. level of the Black Diamond. The 

shaft of the Arizona Venture has reached a depth of 570 ft. 
At the 600-ft. level a station will be cut and the orebody will 

be developed. The financing of the Copper Valley Mining 

Co. has been arranged. Work will commence immediately on 
the road from the mine to Skull Valley station and the shaft 

on the Snow Drift claim will be sunk on the 500-ft. level. 

The south cross-cut on the 700-ft. level of the Verde Combina- 
tion is 10 ft. in the body of quartz carrying iron pyrite and a 
little chalcopyrite. It is estimated that the contact is about 

15 ft. ahead of the present face. The Arizona Power Co. 

has finished the new electric-power line into the Bradshaw 
mountains. The line is to be extended south into Tiger camp. 
The management of the Arizona Binghampton has de- 
cided to continue sinking the main shaft from the 600-ft. level 



to the 1200-ft. level. The present output is 175 tons per day; 

it runs 3J% copper. Funds have been raised to continue 

development at the Montezuma mine at Crown King. The 

Palo Verde copper mine in the Black Canyon district is now 
being worked. Ten tons of ore per day from the old dumps 

is being shipped by motor-truck to Glendale. Four feet of 

fair ore has been struck in the cross-cut which the Jerome 
Copper Co. is driving to cut the main orebody at the contact. 

A new compressor and hoisting engine has been purchased 

by the Jerome Superior. 
Prescott, December 29. 

YUMA COUNTY 

(Special Correspondence.) — The new 300-ton mill at the Red 
Cloud Consolidated Mines Co., is in operation. It is estimated 
that there is sufficient ore developed on the Red Cloud ore- 
body to run the mill for five years. Another orebody to the 
south has two years' supply of ore developed. The ore is sil- 
ver-lead but carries some gold and molybdenum. The Cob- 

rita Copper Co. is sinking a shaft on the 200-ft. level to open 
up a shoot of high-grade ore that was cut under the old man- 
agement. The ore-shoot in the drift shows a width of two feet 
and runs 17% copper and $15 in gold. T. J. Rogers has in- 
terested Prescott people in financing his Emery group of 
claims in the Buckskin mountains. In the past eight months 
six carloads of copper-gold ore has been shipped from the 
property. The present backers have agreed to install a com- 
pressor and other machinery, and drive the adit 400 feet. 

Bouse, December 31. 

CALIFORNIA 

ELDORADO COUNTY 

(Special Correspondence.) — A vein of an average width of 
15 in. assaying $21.12 gold and 7.02% copper has been opened 
on the Sporting-Boy lode claim, according to Frank C. Fox, 
the manager. The vein extends 1400 ft. on the claim, and pans 
free gold for its entire length. The property is being system- 
atically developed by a double-compartment shaft, for pre- 
liminary work, three stamp-mills will be erected with which 
to make mill-tests of the ore as the development of the vein 
progresses. The property is situated about five miles west of 
Placerville, on the lower road to Coloma, in the Cold Springs 
district. 

Placerville, January 2. 

KERN COUNTY 

(Special Correspondence.)— John W. Kelly has discovered 
platinum in a placer mine at the head of Cuyama valley. The 
material was identified as platinum in the Kern county assay 
office. 

Bakersfield, January 3. 

PLACER COUNTY 
(Special Correspondence.) — After being idle for 33 years the 
Rising Sun quartz-gold mine, one mile west of Colfax, is active. 
The property was lately taken under lease by D. A. Russell 
and Lee Gray of Colfax, and is being operated on a royalty 
basis by Martin & Hathaway of Nevada City. A 10-stamp 
sampling-mill and cyanide unit have been installed and good 
ore is being developed. Particular attention for the present

will be devoted to milling of ore from the old dumps and re- 
treatment of large quantities of old tailing. The Rising Sun 
is 725 ft. deep, and the mine is said to have produced $1,500,000. 

Several properties in the Last Chance district are active, 

including the Home Ticket, Pacific, and other good producers. 
Large quantities of supplies have been stored for the winter 
season; the unusually favorable weather of the past few weeks 
has facilitated operations. 
Colfax, January 7.

PAET OF COLORADO 

$12.45 per ton. This heavy tonnage was made possible by the 
treatment of low-grade dump and ore rejected by the mills of 
the Cripple Creek district. The two mills of the Portland Gold 
Mining Co. alone treated 476,050 tons and recovered $899,255. 
The Victor mill, on Battle mountain, treated 224,195 tons aver- 
aging $2.1S per ton, and the Independence mill, originally 
built by the British Corporation Stfatton's Independence, 
Ltd., but re-modeled by the Portland company, commencing in 
May, treated 251, S55 tons averaging $2.08 per ton. Other 
local milling plants brought the total tonnage of low-grade 
ores treated to 494,500, with an average value of $2.11 per ton, 
and a total bullion value of $1,045,294. 
Eight mining companies of the Cripple Creek district paid 



dividends amounting to $2,674,441 during the year. The com- 
panies and the respective rates and amounts follow: Cresson 
Consolidated twelve dividends of 10c. per share, $1,464,000; 
Golden Cycle twelve dividends of 3c. per share, $540,000; 
Portland Gold Mining Co., four dividends of 3c. per share,. 
$380,000; Vinieator Consolidated four dividens of 3c. per share, 
$180,000; Granite Gold Mining Co. three dividends at 2c. per 
share, $49,500; United Gold Mines Co. one lc. dividend, $40,000; 
Doctor-Jack Pot Mining Co. one lc. dividend, $28,441.42; Jack. 
Pot Mining Co. one dividend, $12,500. The last named company- 
owns 1,000,000 shares of Doctor- Jack Pot Mining Co. stock and 
the dividend was paid from this company's dividend. 

At the Vindicator Gold mine the Golden Cycle and Vindicator 
No. 1 shafts continue to produce ore at the bottom levels, 
1950 ft. in the Vindicator and 2100 ft. in the Golden Cycle. 
These deep discoveries have led to deeper development on other 
properties. The shaft at the Rose Nicol on Battle mountain 
has been sunk to 1000 ft. by the Camp Bird company. The 
Modoc Consolidated Co. has its new vertical Frankenberg 
shaft completed and timbered to a depth of 1100 ft. The 
Millasier Mining Co. has sunk the Clyde shaft on Battle moun- 
tain to a depth of 1500 ft., and the Cresson Consolidated has 
sunk the main shaft to 1750 ft. and has added an ore-reserve 

estimated at $1,000,000. The Roosevelt tunnel of the Cripple 

Creek Deep Drainage & Tunnel Co. has been advanced 1800 ft. 
The heading is now in Rose Nicol territory, on the north- 
western slope of Battle mountain, a total distance of 23,715 
ft. from the portal. The work was started in July 1907. The 
flow from the tunnel has dropped to 4000 gal. per minute and 
the district has been effectively drained to a depth of 2000 ft. 
Mining operations during the past year have been handi- 
capped by labor shortage, many miners having left for silver, 
copper, and zinc camps, where a higher scale of wages obtains, 
although the scale was raised in the gold camp to a minimum 
of $3.50 per day. Operating expenses were further increased 
by the high cost of explosives and mining supplies. New 
work, however, has been undertaken, in several sections of the 
district, and the prospects for 1918 are for normal conditions 
and production. 

Cripple Creek, January 5. 

In the Cripple Creek district Carl Evans, superintendent for 
the United Gold Mines Co., has opened a new body of milling- 
grade ore at the 500-ft. level of the Wild Horse mine near 
Midway, on Bull hill, and has commenced hoisting. A ship- 
ment of the ore will be loaded out shortly, and with the shoot 
holding up as expected, production will be steady. The de- 
velopment work at the 1250-ft., or bottom, level continues to 
he satisfactory. 

KANSAS 

CHEROKEE COUNTY 

Some rich blende assaying 64% zinc has been taken from the 
Merrill mine south-west of Baxter Springs. The ore that 
assayed so rich was in the form of crystals and was almost 
prismatic. The average assay record of the ore in this mine 
is higher than many others which are considered good pro- 
ducers. The Merrill Mining Co. is capitalized at $750,000 and 
was the first mining concern in this field to put up a lodge for 
the members of the firm, and another for the workmen and 
mine operators. The orebodies were discovered in the drill- 
holes at the 160-ft. level. In one hole the drill-cuttings indi- 
cated a 41-ft. face of lead and underneath a 23-ft. face of jack. 
The members of the company are W. E. Merrill, president; 
G. Huttig, secretary and treasurer; A. C. Wallace, vice-presi- 
dent. 

The Dick Turpin concentrating plant, situated on a lease 
of the Riseling land, south-west of Joplin, has been purchased 
by the American Metal Co. and will be moved in the near 
future to the company's recently acquired leases west of Baxter 
Springs. The Dick Turpin mill was built by D. W. Sparks and

associates about two years ago and is one of the good mills of 
the district. It will be moved to a trad o! the R. !'. Hartley 
land, where a mill-site has been graded. 

Final details in the sale ot the Miami Zinc Syndicate's tract 
west of Baxter to the American Metal Co. have been closed. 
The purchase price has not been made public. 

MISSOURI 

JASPER COUNTY 

The Butte-Kansas mining plant at Waco was destroyed by 
fire on Christmas morning, with a loss estimated at $75,000. 
There was $50,000 insurance. The origin of the fire is un- 
known. The mill was completed only a week ago and had 
just started making concentrate. It was a 400-ton plant, being 
one of the good ones of the field, and was built on the Coyne 
lease of Hurlbut land, just north of the Liberal mine and south 
of the Waco Mining Co. property. A portion of the equipment 
was obtained from the Meadville Mining Co. property, at Car- 
terville. but much new machinery had been added and the 
plant was thoroughly modern throughout. E. A. Wiltsee was 
manager of the property, which is owned by Eastern capital- 
ists. As the ground is exceedingly rich it is expected that the 
mill will be re-built at an early date. 

An official statement from the management of the Unity 
and Concord Mining companies of Webb City as to the pro- 
duction of the two properties during the twelve months clos- 
ing December 31, shows that the year has been a good one. 
There has been a total tonnage of concentrate produced amount- 
ing to 5559 tons, or more than 11,000,000 lb. The two mines 
are owned by virtually the same people, including Phil 
Gray and associates of Webb City. The Concord mill is of 300 
tons capacity and is situated in the south part of Carterville. 
It was completed last spring and was placed in operation in 
April. The production since that time has amounted to 3,294,- 
880 lb. of zinc-blende and 782,000 lb. of lead. The Unity mine 
is situated in the Oronogo bottoms, north of Webb City, just 
north of the D., C. & E. property, and has been going steadily 
for the past year, the mill having been built in 1916. In size 
it is approximately the same as the Concord, but the produc- 
tion, due to the more extended operation, has amounted to 
5,474,750 lb. of zinc concentrate and 1,649,430 lb. of lead. Both 
mines are sheet-ground properties, producing a high-grade 
concentrate and with ore that has been giving a good recovery 
for sheet-ground properties. 

MONTANA 

LEWIS AND CLARK COUNTY 

(Special Correspondence.) — Severe cold has given place to 
warmer weather and the result is that more ore is moving 
from the various mines. The Helena mine in Grass Valley 
is sending out two carloads of silver-lead ore per week and 
there is a large tonnage in sight. A new skip with a ca- 
pacity of two tons is being used. W. F. Word is general man- 
ager and consulting engineer. The shaft is to be deepened to 
400 ft. before spring. The Cruse Consolidated and Rock Rose, 
adjoining claims, are sending ore to the smelter. In the 
Scratch Gravel hills four mines are shipping. The principal 
mines are the Thomas Cruse Developing Co. property and the 
Scratch Gravel Gold. The former is mining ore on the 600-ft. 
level and the latter is taking ore from the 300-ft. stopes. In 
Marysville camp the Barnes-King is working the Shannon and 
the Piegan-Gloster. The product is milled at Gloster. The 
returns from all of the mines worked by the Barnes-King are 
upward of $100,000 per month. The Mt. Washington mine at 
Wickes is sending out two carloads of silver-lead ore to the 
smelter daily from the SOO-ft. level.— — A rich strike of silver 

ore has been made in the old camp of Elkhorn. A discovery 

has been made recently in the Gould placers above Rimini. 
The vein was discovered by accident in excavating for a reser- 



voir. The shaft is down GO ft.; the ore assays 500 oz. In silver 
and $100 in gold.

Miami, January 5. 

An excellent ore-cave has been discovered in sinking a shaft 
on the Blackhawk Lead & Zinc Mining Co. lease on the Walker 
land, south-east of Picher. The cave was struck at 228 ft. It 
is 10 ft. from the floor to the roof and the sides, roof, and

bottom all are lined with crystallized lead and zinc ore. Ac- 
cording to drill-holes put down on the lease a 30-ft. deposit of 
ore is apparent. The cuttings were said to assay around 18%. 
The orebody was found at 218 ft. and went down to 248 ft. 
J. Younts of Sikeston, Missouri, is president and Jack Williams 
of Miami, secretary and treasurer. R. C. Ulmer is the super- 
intendent. The shaft already down will be used as a mill-shaft. 
A field shaft will be started at once on a nearby portion of the 
lease. 

The Greening Mining & Smelting Co. is constructing a con-

NEVADA 

ESMERALDA COUNTY 

(Special Correspondence.) — The underground force at the 
Red Hill Florence has been increased and preparations begun 
for vigorous developments on the 700-ft. level. Stations will 
be cut on the 600 and 700-ft. levels and drifts started from 
both points to seek the Florence vein. Several drifts and 
raises are advancing from the 500-ft. level, to explore promising 
ground and to thoroughly develop the rich shoots lately opened 
by lessees. An 18-in. vein of sulphide ore has been opened

on the 700-ft. level of the Silver Pick, and appears to be the 
same vein that has been developed on the 250-ft. level. At 
this point ore assaying $6 to $16 per ton in gold is exposed. 
The drift is advancing to seek the junction ot two veins on 
the 250-ft. level. A drift and raise are being driven from the 
500-ft. level, the raise intended to connect with the 250-ft. 

workings. Splendid ore continues to develop in the Tonopah 

Divide mine in the Gold Mountain district, 38 miles south of 
Goldfleld. At a depth of 450 ft. the vein is said to be 20 to 

25 ft. wide, averaging $15 to $25 per ton in gold and silver. 

On the 125-ft. level of the Butte Goldfleld the vein has widened 
to two feet, assaying $14 to $16 per ton in gold. An accom- 
panying 6-in. vein assays $64 per ton. A station will be estab- 
lished at the 150-ft. point and drifts thrown out to develop the 

orebody. L. L. Patrick, of Goldfleld, is president. The 

Silvermines Corporation, operating at Hornsilver, is sending 
150 tons of ore daily through the mill and reports an excellent 
extraction. The hoist will be replaced shortly by a hoist 
driven by a high-powered engine operated by compressed air. 
The company is preparing to use a 150-ft. cross-cut for storage 
of compressed air, sealing the cut with a concrete bulkhead. 
By this arrangement a single pipe will be used for charging 
the cross-cut and delivery of the compressed air to the equip- 
ment. As soon as the shaft attains a depth of 700 ft. a sta- 
tion will be cut and sinking continued to the water-level. 
S. E. Brady is manager.

UINTA COUNTY 

The Crane Shale Oil Co. of Reno has purchased 200 acres 
of oil-shale deposits at Watson from New York and Salt Lake 
City owners for $100,000. The deposit is said to have a depth 
of 80 ft. The shale will be treated by the new Crane process. 

WASHINGTON 

FERRY COUNTY 

While engaged in the development of its property, the 
Virginia Mining Co., operating near Danville, has received 
$27,000 net for ore shipped to smelters this year. The total 
output is 2000 tons. The ore of shipping grade is in a body 
4 to 8 ft. wide on the foot-wall and 4 to 14 ft. wide on the 
hanging wall. One of these bodies is 150 ft. long. This is at 
a depth of 225 ft. Another level is expected to enter these ore- 
bodies at a depth of 500 ft. It will probably reach the objective 
within 60 days. The ore at 225 ft. contains 2J to 3% copper 
and $18 to $22 in gold per ton. Shipments have been proceed- 
ing at the rate of two carloads per week. The last two cars, 
composed of 44 to 50 tons, brought more than $2000 after the 
deduction of freight and treatment charges. The property was 
acquired on a bond and lease for $50,000, expiring in June 
1920. The company has paid a royalty of $2700, which is at 
the rate of 10%, and met the bond payment recently. It ac- 
quired an adjoining property for $6000 this fall. Twelve men 
are employed. The number will be increased when the ground 
is opened on a broader scale. Buildings, ore-bins, and a com- 
pressor were erected this year. About 800 ft. of work has 
been performed in the lower adit. 

CANADA 

BRITISH COLUMBIA 

The Granby Consolidated Mining,, Smelting & Power Co. 
produced 2,886,489 lb. of copper in November. The Anyox 
plant produced 2,458,841 lb., and the Grand Forks plant 427,648 
lb. of this quantity. 

The production for November is about 75,000 lb. less than 
that for October and. about 320,000 lb. less than November 
1916. The reduction results from a lessened output from the 
Grand Forks plant, the output of Anyox in November having 



been greater than in October. This is accepted as an indication 
that some of the changes at Anyox have been completed. 
Granby has adhered to its dividend rate of $10 per annum; it 
has but 150,000 shares of issued capital and $2,514,400 bonds 
due in 1928. Its quick assets on June 30 were $5,219,000. At 
$66 per share %nd par for the bonds, less the above quick 
assets, the whole Granby mine, smelter, converting, and power- 
plants are given a valuation of but $7,500,000, or less by 
$1,500,000 than the combined profits of the fiscal years of 1916 
and 1917. At the annual meeting of Granby stockholders last 
October, it was stated that the operation of the contemplated 
coal and coke company was expected to effect a saving of 
possibly 50% in the cost of coke for the company's own re- 
quirements. The production of coal will probably exceed the 
quantity consumed by the company in its metal operations. 
The Grand Forks property has become less important as an 
operating factor for the Granby, as revealed in the constantly 
declining copper output from month to month. Last month's 
yield of less than 500,000 lb. was the smallest production 
recorded for over a year, barring the July total of 280,000 lb. 
At that time the property was in process of resumption after 
a two months' idleness caused by a strike. 

The following amounts have been disbursed in dividends by 
some of the principal mines during 1917: 

Con. M. & S $ 996,503 

Granby 1,499,848 

Hedley 240,000 

Le Roi No. 2 29,199 

Rambler-Cariboo 35,000 

Standard 300,000 

Utica 64,000 

Total $3,164,550 

Increase of the capitalization of the Lucky Jim zinc mines 
to 6,000,000 shares from 2,500,000, par value $1 each, is pro- 
posed in a special resolution to be presented to the stock- 
holders at a general meeting to be held at Victoria, January 
12. The increase will enable the company to absorb $125,000 
in bonds, discharge other obligations, and provide a surplus of 
treasury stock for the improvement of the property, it is 
stated in a circular issued by Walter J. Nicholls, secretary. 

One of the best strikes of recent years in the Slocan district 
has been made on the Hidden Treasure claim of the Noonday 
Mines Co., according to a report from Kaslo. More than seven 
feet of ore has been exposed at a depth of 400 ft. A foot of the 
body has an average content of $7000 to $8000 net to the car- 
load of 30 tons with silver at 86c. Ore from the same vein, lost 
15 years ago, yielded $5000 net to the carload when the price 
of silver was in the neighborhood of 55c. The Hidden Treasure 
adjoins the Richmond-Eureka of the Consolidated Mining & 
Smelting Co. which is credited with a yield of $1,500,000 in ore 
taken from a shoot of this kind. Search for ore in the Hidden 
Treasure began many years ago, and when found it disap- 
peared after producing about $40,000 worth of ore. The search 
was renewed by the Noonday company two years ago. Work- 
ing on another theory Bruce White, manager, sought the body 
in a different section than that explored by the pioneers. He 
operated steadily, although with a struggle at times, removed 
$16,000 in the course of the investigation, and had no indebted- 
ness when the ore was struck several weeks ago. The shoot 
has been followed 30 ft. The milling ore is of a superior 
quality; it contains lead and silver and little zinc. This ore 
will be concentrated in the mill of the Slocan Star if arrange- 
ments can be made with that corporation. The properties are 
on the opposite sides of the same hill, and their workings are 
so situated that the removal of Noonday ore can be done with 
economy through the Slocan Star mine. The course and situa- 
tion of the body suggests that it may be found in the Slocan 
Star.

William Hague, Lieutenant in the 116th Regiment of En- 
gineers, died of bronchial pneumonia on January 3 in France. 
He graduated from Harvard in 1904 and therefore was about 35 
years old. The only son of the late James D. Hague, he fol- 
lowed worthily in his distinguished father's footsteps and had 
already given more than a promise of being an unusually 
capable and useful man. As soon as war was declared he 
volunteered for active service and went to the training camp, 
resigning his position as managing director for the North Star 
Mines company at Grass Valley. A man of high character and

The Joplin lead-ore market has shown greater strength and the pur- 
chases made have been extremely heavy, reaching such proportions as to 
absorb practically two-thirds of the surplus stock now held in the district. 
While all of this surplus is not moved, it is believed that now the lead 
surplus has been reduced to 2000 to 2500 tons now unsold. With the 
present conditions of the roads it is not believed that all purchases will be 
loaded out under 15 to 30 days. The base price for the major portion of

A committee has been appointed by the South Western Mining Safety 
and Sanitation Association of Webb City. Missouri, to investigate the pos- 
sibilities of substituting spelter for copper, tin, and other metals for 
various purposes. Movements are on foot to interest capital in the build- 
ing of a zinc-rolbng mill. The price of sheet zinc has been for a long 
time ruling at much higher than the normal cost of producing sheet zinc, 
on account of there being only two producers of this material. It is be- 
lieved that the use of sheet zinc could be enormously increased if the 
price of the sheet metal were more moderate.

Samuel Montagu & Co. says: An advance specimen of the one rupee note 
has been received in India from the India Office in London. The note 
measures five inches by three and a half inches, and has an engraving of 
the head of the King Emperor in the left-hand top corner, similar to that 
on the silver rupee. There is a pink medallion in the centre of the note, 
across which the phrase 'One Rupee' is printed, while the numeral "1' is 
printed in opposite corners so as to facilitate counting. The Indian mints 
have been engaged in turning out munitions for the supply and transport 
corps and other divisions: the advantage, therefore, of lessening then- 
duties, by the issue of small notes instead of coins, is obvious. Notwith- 
standing their special activities in munitions, the mints turned out in 
1916-17 R. 207.737.326 in silver coin, as against R. 16.202.199 in the 
previous year. 

Mining companies arc requested to advise us of new dividends declared 
and to furnish complete figures for dividend disbursements made during 
the year 1917. in order that our monthly dividend-list may be kept up to 
date. .

Eastern Metal Market 



January 2. 

The markets are all decidedly quiet as the new year begins. 
The last week in the old year has been probably the quietest 
of all, as is usually the case. 

Copper at controlled prices is moderately active. 

Tin continues alarmingly scarce, and high, at nominal prices. 

Lead is dull but firm. 

Zinc has a better tone but is inactive. 

Antimony is quiet. 

In the steel trade the announcement has been made by the 
President that the present schedule of fixed prices will con- 
tinue in effect three months longer, and that an agreement has 
been entered into whereby, on contracts made in the coming 
three months, prices would be revised in deliveries after 
April 1, 191S, to conform to any changes that might become 
effective on that date. Possibly 100,000 cars may be ordered 
for its railroads by the Government, now that it has taken 
control of them. Additions to the steel capacity of the country 
in 1917 were larger than expected. There were 97 new open- 
hearth furnaces completed in 1917, with an estimated capacity 
for producing 4,326,500 gross tons of steel ingots. The Steel 
Corporation furnished 1,220,000 tons of this total. The in- 
crease in 1917 was 4,205,000 tons, so that 1917 constitutes a 
record. New blast-furnaces blown in during 1917 were 14, 
with an annual capacity o£ 2,520,000 tons, against only five 
new furnaces in 1916. Sixteen more are now under construc- 
tion. 

COPPER 

The copper market begins a new year in a decidedly stabil- 
ized and apparently comfortable and satisfactory condition. 
This has been true for some time, and is due to Government 
regulation of prices and distribution. It is apparently a 
settled fact that there will be no change in prices for a con- 
siderable period; at least no reduction will be made, and the 
trade feels that it can proceed safely and freely for a while. 
Sales are being made regularly to the trade, with Government 
and Allied needs having the priority at the established price 
of 23.50c. per lb. for carload lots or more, and at 24.674c. for 
less than carloads and for delivery in the first quarter. Many 
in the trade have reason to believe that the supply of copper 
will be sufficient to cover all reasonable needs. It is also 
stated that the producers have on their books orders for the 
Government's requirements for the next six months. The fuel 
question may result in some lessening of activity among con- 
sumers using copper for non-essential purposes, but this may 
not prove a big factor in lessening consumption. December 
exports seem likely to have been larger than the November, 
which were 38,638 gross tons. The total for 1917 to December 
1 was 448,596 tons, against 327,310 tons for the whole of 1916. 
The monthly exports have been 40,781 tons to December 1. 
For several months the London market has been unchanged at 
£125 per ton for spot electrolytic. 
TIN 

Tin of all grades continues scarce, and the market, as the 
new year enters, is nominally higher than at any time in its 
history. In this district it is nominal at 85 to 86c, New York, 
for spot Straits with other grades correspondingly high. No 
metal is being offered for spot delivery except a little Banca 
tin at about 84c. The British government has apparently 
taken some important action, the details of which are lacking 
so far. It appears probable that all speculation in the metal 
has been forbidden and that sales in that country will be per- 
mitted only for consumers' requirements. It also probably 
means that the American consumers' names will not have to be 



passed upon by the London Tin Committee, leaving consump- 
tion entirely to the American Iron and Steel Institute. It Is 
probable that the result of this action will be to insure more 
adequate supplies to this country, as well as the elimination of 
permits with their difficulties and delays. Arrivals of tin to 
December 27 were 1705 tons, with 4400 tons afloat. The last 
cable from England, on December 28, showed spot Straits at 
£295 per ton, which compares with £309 10s. on December 21, a 
decline of £13 10s. 

LEAD 

The firmness which has characterized the lead market for 
many weeks still rules as the new year opens, and prices are 
at unchanged levels. The quotation for early delivery in the 
outside market is 6.50c, New York, or 6.35c, St. Louis, with 
the leading interest asking 6.25c, New York. The market is 
only moderately active, with a fair-sized demand during the 
past week for lots varying from carloads to 100 tons. There 
seems to be no trading in large volume. The industry was 
free from price-fixing in 1917, but it will be imposed in 1918 
if a runaway market develops, of which there seems little pros- 
pect now. A lesson in this was learned in 1917. The pre- 
liminary estimate of the 1917 lead output by the U. S. Geo- 
logical Survey is expected soon, and it is awaited with interest. 
Some put the total at 625,000 tons, against 571,134 tons in 

1916 and 550,055 tons in 1915. The output in the first half of 

1917 was 306,062 tons and it has probably been heavier in the 
last half. 

ZINC 

A slightly better tone pervades the market at the beginning 
of the new year but the market is practically at a standstill, 
with no desire by buyers to buy nor by sellers to sell. The 
cause of these conditions is probably the high bids on the 
Navy's 1000 tons of grade C zinc, and the probably similar 
bids on the 4000 tons of the same material for the Army, 
though these are not known as yet. It is stated that only a few 
producers offered bids on the latter order. It is felt also that 
this fairly large interest in the market on the part of the 
Government is a forerunner of more buying of other grades. 
Irregularity as to quotations on prime Western for early 
delivery characterizes the situation. Some ask as high as 
8c, St Louis, but the market is probably quotable at 7.62Jc, 
St. Louis, or 7.87Jc, New York, at which a few small sales 
have been made. The year 1917 has not been altogether an 
unsatisfactory one, and the new year begins with prices only 
a little above the lowest level of 1917. 
ANTIMONY 

Late last week a consumer made inquiry for a fairly large 
amount for prompt delivery, on which later it is understood 
some fairly low quotations were made. The prices are there- 
fore easier at 14.50 to 14.75c. per lb., New York, duty paid, for 
Chinese and Japanese grades for prompt delivery. War de- 
mand is more uncertain than ever for our own needs in par- 
ticular. 

ALUMINUM 

There is no interest in aluminum and No. 1 virgin metal, 
98 to 99% pure, is unchanged at 36 to 38c. per lb., New York, 
for early delivery. 

ORES 

Tungsten: There is very little news. The market continues 
strong after the demand noted last week with 60% concen- 
trates selling at $24.50 per unit for wolframite, and $26 per 
unit for seheelite. Ferro-tungsten is quiet at unchanged 
prices.

CALOL ASPHALTUM IN PAVEMENT 
CONSTRUCTION 

This is the title of a bulletin, No. S, of the Department of 
Asphaltum of the Standard Oil Co. of California. We have 
made reference to it before, and have intimated that the brief 
statement it contains in regard to the properties and use of 
asphaltum is based upon an elaborate investigation, both 
physical and chemical, by a scientific staff of very high calibre. 
No more thorough research-work has been done anywhere in

ASPHALTUM MELTING-TANKS 




SECTION OF ASPHALTIC CONCBETE PAVEMENT 

America than has been conducted during the last few years 
in the splendid research laboratories of the Standard Oil 
Company of California. The pamphlet constitutes a safe and 
practical handbook for the road builder and contractor, giving 
sufficient details of the mechanism and equipment needed for 
the business, accompanied with abundant illustrations, and 
supplying practical instructions in regard to the making of 
the mixtures adapted to different classes of service, erection 
of plant, lay-out of plant, and many similar points. It is par- 
ticularly explicit in regard to the necessary equipment, such 
as elevators, conveyors, driers, screens for the aggregate, hot- 
storage bins, mixers, melting-tanks, pumping, asphaltum, and 
other matters of vital importance in the business. Finally, 
the company recommends, as a result of the elaborate tests 
that have been made with a view to obtaining from Californian 
oils a thoroughly reliable asphaltum for pavements, an article 



known as Calol asphaltum 'D' grade. This has the following 
characteristics: 

Penetration, No. 2 needle, 100 gm., 5 sec, at 77°F., 40 to 90°. 

Solubility in carbon disulphide (CS,), not less than 99%. 

Solubility in carbon tetrachloride (CC1,), not less than 98.5%. 

Ductility of a sample briquette, 1 sq. cm. in cross-section, 
elongated at 5 cm. per min. at 77°F., not less than 75 cm. 

Evaporation from 50 gm. in 5 hr. at 325°F. in a dish 5.5 cm. 
(2J in.) diam. and 3.5 cm. (1J in.) deep, not more than 3%. 

Penetration of sample after evaporation test, not less than 
350°F. 

HOrders may be placed for Calol, asphaltum 
'D' grade, with a range of 10° penetration, that 
is, from 40 to 50, 50 to 60, 60 to 70, 70 to 80, 
or 80 to 90, according to the choice of the 
engineer. It is shipped either in wood barrels 
or tank cars. 

Details of tests for pavement materials oc- 
cupy 25 pages in the pamphlet. These are in 
accordance with standard tests adopted by the 
U. S. Office of Public Roads, and the American 
Society for Testing Materials. The tests in- 
clude hardness, resistance to wear, and tough- 
ness of rocks, together with cementing value 
of rock with water and w ; th asphaltum, as well 
as the cementing values under compression. 
For asphaltum the consistence or penetration, 
and tests of solubility, ductility, volatilization, 
and also the flash tests are given. Accom- 
panying these are descriptions of the modus 
operandi of the tests and illustrations of the 
equipment required. The book is accompanied 
with a classified index, both of subject matter 
and illustrations. It is a contribution of prac- 
tical engineering literature that will be of great 
assistance to municipal and county officers, and 
to contractors everywhere having to do with 
the construction of paved streets and roads. 
It will also appeal to mine managers who have 
problems of surfacing roads for facilitating 
local haulage. 



DECISION ON THE DEISTER PATENTS 



The District Court of the United States for the District of 
Indiana has handed down a decree in equity, No. 201, in the 
case of Deister Machine Co. v. Deister Concentrator Co., hold- 
ing valid and infringed certain claims in patents issued to 
Emil Deister and William F. Deister, as follows: claim 4 in 
Patent 1,040,164; claim 1 in Patent 1,040,165; and claims 1, 
4, and 5 in Patent 1,088,6S5; and a perpetual injunction is 
issued against the defendant. Article 5 of the decision states 
the infringement as given below: 

That the Deister Concentrator Company infringed upon 
claim 4 of said Letters Patent No. 1,040,164, viz: "4. A con- 
centrating table having its main surface in a single plane and.

suitably inclined in combination with means for distributing 
material across the head of the table, riffles arranged at such 
an angle to the flow of material from the head as to divert the 
minerals toward the mineral discharge edge, a plateau having 
its surface above but substantially parallel with the general 
surface of the table and arranged with its inner edge at an 
angle less than ninety degrees to said riffle, and riffles extend- 
ing across the plateau," upon claim 1 of said Letters Patent 
No. 1,040,165, viz: "1. A concentrating table inclined down- 
wardly from its head and upwardly from its rear side, in com- 
bination with means for uniformly distributing the material 
to be treated across the upper end, riffles arranged transverse 
of the main surface of the table, and a plateau having its sur- 
face above but substantially parallel with the main surface, 
and arranged to intersect the line of movement of the material 
due to the vibrations of the table;" and upon claims 1, 4, and 
5 of said Letters Patent No. 1,088,685, respectively, viz: "1. 
A concentrating table having in combination therewith a 
plurality of plateaus arranged transverse of the lines of move- 
ment of the values toward the mineral discharge edge, and 
having their surfaces higher than that of the main or strati- 
fying surface and the surface of each succeeding plateau being 
higher than that of the preceding plateau, the front edge of 
the final plateau of the series forming the mineral discharge 
edge and a plateau or plateaus intermediate the main sur- 
face of the table and the last plateau being adapted to permit 
of a further stratification of the material and to deliver con- 
centrates as a stratum to the plateau having the mineral 
discharge edge." "4. A concentrating table, having in com- 
bination therewith a plurality of plateaus arranged transverse 
of the lines of movement of the values toward the mineral 
discharge edge, the main or stratifying surface of the table 
and the surfaces of the plateaus being in different but parallel 
planes and the rear edges of the plateaus being beveled or in- 



clined to facilitate the upward and onward movements of the 
values, the front edge of the final plateau of the series form- 
ing the mineral discharge edge and a plateau or plateaus 
intermediate the main surface of the table and the last plateau 
being adapted to permit of a further stratification of the 
material and to deliver concentrates as a stratum to the 
plateau having the mineral discharge edge." "5. A concen- 
trating table, having in combination therewith a plurality of 
plateaus arranged transverse of the lines of movement of the 
values toward the mineral discharge edge and having their 
surfaces higher than that of the main or stratifying surface, 
and the surface of each succeeding plateau being higher than 
that of the preceding plateau, and riffles arranged on the main 
or stratifying surface and extending onto the plateau next 
adjacent to the mineral discharge edge, the front edge of the 
final plateau of the series forming the mineral discharge edge 
and a plateau or plateaus intermediate the main surface of 
the table and the last plateau being adapted to permit of a 
further stratification of the material and to deliver concen- 
trates as a stratum to the plateau having the mineral dis- 
charge edge;" and upon the exclusive rights of the complainant 
under the same. 

The Monroe 'Calculating Machine' was given a well-de- 
served notice in our last issue, in an article written by R. M. 
Farmer. The facts will not he misconstrued by an under- 
standing public, in view of the plain intent of the statement, 
despite an unfortunate error that crept into the printed page, 
twisting Mr. Farmer's affirmation as to operating speed into 
the exact reverse of the truth. Beginning with line 16, column 
1, on page 30, the sentence should read: "It has been shown 
that the operating speed of a Monroe calculating machine is 
greatly in excess of that obtained by other methods, but the 
chance for inaccuracy has been brought to an irreducible 
minimum as well."

G-E Complete Electrical Equipment 

for Cranes Assures Speed with Safety 



G-E engineers have studied crane require- 
ments and designed electrical apparatus to 
meet known operating conditions. Every 
requirement for stopping or starting, and the 
entire operating cycle is fully met by specially 
designed apparatus. 

Motors 

Interpole motors, capable of standing heavy over- 
loads, are manufactured in any speed or horse- 
power needed. These motors have split frames and 
large handholes for accessibility, and can be dis- 
assembled without disturbing back gearing. 

Brakes 

G-E crane motors are furnished with automatic 
solenoid brakes which work without jar or shock 
and make automatic compensation for brake shoe 
wear. Brake shoes made of metallized asbestos 
compound give a high co-efficient of friction with 
but little wear. 



Resistors and Protective Panels 

The G-E standard for crane equipment is to sup- 
ply all resistor sections of uniform size, which re- 
duces the number of spare parts needed to a mini- 
mum. The design of the cast iron grid resistance 
units is such as to avoid the danger of short cir- 
cuits by vibration and double insulation protec- 
tion against grounding is provided. 
Protective devices are furnished in small panel 
units which can be attached in any convenient 
place. A push knob on master panel opens line in 
an emergency, and overload protection is afforded 
at all times. 

Controllers 

Horizontal or vertical handle controllers are fur- 
nished which are absolutely reliable and very ac- 
cessible. They are equipped with magnetic blow- 
outs, arc chute protecting covers, and many refine- 
ments which twenty years of controller building 
suggested. 

Your inquiry for complete electrical crane equip- 
ment is solicited.

nnHE 116th meeting of the Institute will be held at 
■*■ New York from February 18 to 21 inclusive. An 
interesting programme has been arranged. 

Z^ 1 OLD production decreased in 1917. The Mint and 
^-*" the Geological Survey estimate the American out- 
put at $84,456,600, which is $8,130,000 less than in 
1916 and the smallest total since 1904, when it was 
$80,464,700. The rest of the world is not likely to have 
compensated for this decline, but statistics are not yet 
available. 

"17" EEN satisfaction has been expressed by the oil- 
■*-*- men of California at the appointment of Mr. Mark 
L. Requa as head of the oil division of the Food Admin- 
istration. He is to direct operations on the oilfields un- 
der Government control. Mr. Requa has had experience 
in the oil business and is thoroughly fitted for the task. 
We join with the mining profession in commending the 
appointment. 

f^ A.RRANZA is said to be offering Clipperton island 
^~ 4 for sale to Japan. The Sefior is usually more astute 
than that. He overlooks the fact that Viscount Ishii 
recently visited this country and obtained recognition 
of what the Japanese papers call "the Monroe Doctrine 
of the East." That balances a counter courtesy on the 
part of Japan, which means that the market for Ameri- 
can islands is limited. If Mexico has any land for sale 
she had better call at Uncle Sam's real estate bureau. 



/"iUR contemporary in London, 'The Mining Maga- 
^-* zine,' is 'carrying on' with manifest vigor, despite 
the many hindrances due to the "War. The issue for 
December, just to hand, is excellent, particularly in 
respect of the engineering drawings that accompany the 
article by Mr. J. "Waring Partington, on the Taylor con- 
centrator at the East Pool mine in Cornwall. Our com- 
pliments to Mr. Edward Walker and to Mr. W. F. 
White, the editor and managing director respectively. 



cumulated credit balance in our favor of $8,115,883,677, 
which is about equal to the total stock of gold in the 
world. In addition to this trade balance the United 
States government received authority from Congress to 
advance something over four billions of dollars to our 
Allies out of the war appropriation of 19 billions. 



"W7~HAT happens to a successful trade paper is illus- 
" trated by our friend the 'Iron Age,' whose first 
issue in January consists of 130 pages of reading matter 
and 718 pages of advertisements. The magazine is two 
inches thick and weighs 5J pounds, the postage on which 
is 5J cents and the cost of paper alone must be 27-J cents. 
It is a comprehensive directory of the iron and steel 
trade. The front cover carries a beautiful steel engrav- 
ing, by the American Bank Note Company, whose 
handiwork on U. S. currency is so attractive to most 
of us. 

/~\N another page we reproduce a contract offered by 
^-' the Minerals Separation company for signature to 
a metallurgist that had invented an improvement in 
flotation. The text speaks for itself. Like the contract 
that the Minerals Separation people attempted to force 
upon metallurgists employed by their licensees, this is a 
rank bluff and an imposition upon the self-respect of a 
technical man. It will be noted that Minerals Separa- 
tion consents to the use of apparatus by its licensees, 
and the inventor is to pay 10% of the selling price of 
the machine to Minerals Separation, and as against the 
privilege of paying 10%, the inventor is not allowed to 
sell his machine to anybody not licensed by Minerals Sep- 
aration, on penalty of a fine of $10,000. It is to laugh ! 
Fortunately, that is what the inventor did, sharing his 
sense of humor with us and our readers. 



A MERICA'S foreign commerce in 1917 amounted to 
■"■ $9,050,000,000, of which three billions only repre- 
sented imports. In the last three years our foreign com- 
merce has reached a total of $22,201,077,067, with an ac- 



rpHE passing of Thomas L. Livermore removes a dis- 
-*- tinguished figure from the mining world. He was 
long the associate of Alexander Agassiz and Quincy A. 
Shaw, and was responsible for the general direction of 
America's most remarkable copper mine, the Calumet 
& Hecla. His force of character, and his exact and 
scrupulous observance of business propriety, made him 
a factor in the copper market and enabled him to throw 
his weight against the policies that at one time tended 



76 



MINING and Scientific PRESS 



January 19, 1918 



strongly in the direction of large combinations to control 
the output of that metal. Colonel Livermore, acting in 
accord with his associates, held to the advantage of inde- 
pendence, thereby encouraging other important copper 
companies to resist the temptation toward amalgamation 
and restraint of trade. It is noteworthy that, of all the 
leading non-ferrous metals, copper has been most nearly 
fiee from pernicious capitalistic control. A contrary 
disposition on the part of Colonel Livermore might have 
altered completely the character of the copper industry, 
to the detriment of this country and of the world. 



T>ROTESTS are being made by the American Mining 
■*• Congress in behalf of the mining industry against 
the proposal to place the direct control of mining opera- 
tions in the hands of the Government. Mr. M. D. Foster, 
of Illinois, chairman of the Committee on Mines and 
Mining, has introduced a bill providing for the control of 
mineral deposits by the President, similar to that pro- 
vided for food and coal in the Pood Act. This bill seeks 
to appropriate $150,000,000 for the purpose stated. The 
idea, it is said, is "to ensure an adequate and continuous 
supply of certain rare metals, such as tungsten, which 
are needed for war purposes." Surely such legislation 
is wholly unnecessary. Statistics demonstrate that the 
operators of mines are responding whole-heartedly to the 
call for the metals needed for munitions, and if further 
increase of production be necessary it can be effected by 
the assistance of the Bureau of Mines, the Geological 
Survey, and other agencies that exist to aid the mineral 
industry of the country. The first result of such an 
enactment would be to place a $1 halo on a number of 
prominent millionaires and cripple the industry with 
unnecessary red tape. Let the President say what 
metals are needed and they will be forthcoming, for the 
mining industry can furnish both the money and the men 
to do it without further legislation or the creation of 
more committees. 



/~^ ERMANY had planned before the "War to violate 
^-^ all manner of anti-trust principles and national 
prejudices throughout the world. "We present demon- 
stration of the Teutonic performance on another page. 
It resembles a spider's web, and was alluring as a market 
into which all were invited in language recalling the 
nursery jingle ""Will you walk into my parlor"? More- 
over, the unsuspecting world did walk in, and through 
this astonishing combination it became possible for Ger- 
many to absorb metallic products in preparation for war 
without exciting suspicion. Many reputable houses in 
the system were wholly unconscious of the use being 
made of them in furtherance of the gigantic plan for 
Germanic imperial dominance, ffhey were found in a 
strong position in the world's markets, and it was deemed 
easier to absorb the advantage of that position by letting 
such firms make money in association with a German 
house whose distant 'metallbank' was invisible. The 
British are now thoroughly awake to the peril of again 
permitting such trade organizations as those created for 



the ultimate purpose of the Prussian machine, a purpose 
that we live to see frustrated. Apart from the national 
question it is clearly dangerous to permit any group in 
any country to control the metal market of the world to 
such an extenV 



r^ OMPAPJSON of metal prices during 1917 as against 
^ 1916 shows that the industry had good fortune: 

1917 1916 

Cents per pound Cents per pound 

Copper 27.52 2S.03 

Lead 9.06 6.88 

Zinc 9.18 13.70 

Tin 61.56 43.26 

Silver 81.23 65.66 

Mercury per flask 106.33 126.89 

The fixation of the price of copper at 23$ cents pulled 
down the average for the year, but not to a calamitous 
degree, owing to the higher prices ruling during the 
first eight months. The beginning of 1918 sees copper 
pegged again at 23$ cents, for word has come from "Wash- 
ington that the Federal authorities have continued the 
same price for another four months. The collapse of the 
spelter market has been the most untoward event of the 
year. Zinc is firm at 7.87 cents, which, however, repre- 
sents a decided recession even from the 1917 average. 
The average price of lead in 1917 was being paid in 
September, but since then the decline has been serious, 
falling to 6i cents during the closing quarter and be- 
ginning the new year at about that figure. "We pro- 
duce so little tin in this country that the price affects 
not the miner but the manufacturer, who has to im- 
port it. The silver market is strong at about 9 cents 
above the average for 1917 and the prospect is good for 
a slightly higher price when the proposed fixation has 
been consummated. Mercury is an important product of 
California, and it is pleasant to record a present price 
that is $24 per flask higher than the 1917 average. All 
that the miner can ask for 1918 is that the prices for 
copper, silver, and mercury may be maintained, and that 
those for lead and zinc should be raised a little, the 
prices of the latter being good as compared with the 
pre-war period but the increased cost of operation offsets 
the apparent advantage. On the whole, the mining in- 
dustry is not suffering from the "War. 



Wildcats 



The felis rufus of mining finance is an interesting 
animal, not only on account of the ravages he causes in 
well-lined pockets, but by reason of his variable tempera- 
ment. He is not always predatory. The dictionary says 
that he is the expression of reckless or unsound finance. 
One definition says: "Originated or characterized by 
wild irresponsible speculation; unreliable or unsafe, by 
reason of reckless financiering." A nefarious motive is 
commonly assumed to be at the back of a feline project. 
In 'Yavapai,' a paper published at Prescott, we read the 
following comprehensive definition. "A wildcat mining 
company is one in which the management raises money,

often by exaggerated and misleading statements, intend- 
ing to use the funds so raised for their personal profit, 
rather than for the development of the property, and 
without regard to seeuriiig an adequate return to in- 
vestors." "Their profit" must refer to the organizers 
of the company, and "investors" is a euphemism for 
'speculators.' Still it is a definition that would be gen- 
erally acceptable. However, malign intent is not a neces- 
sary characteristic of the 'wildcat,' for that term is now 
used sometimes simply to indicate a long shot, the locat- 
ing of claims far from points of actual discovery, the 
taking of a sportive risk in mining. We remember being 
threatened with a libel suit because we said that the 
Great Boulder Proprietary mine, in Western Australia, 
started life as a wildcat. To the lawyer that called upon 
us we explained how 'wildcat' was used in Nevada as a 
term for riskiness in which deception was not involved. 
We were reminded of the senator from Nevada who used 
an epithet that, according to Owen Wister in 'The Vir- 
ginian,' must be accompanied by a smile lest it start 
gun-play ; how a committee of senators was appointed to 
inquire into the scandalous incident; and how the col- 
league of the senator from Nevada testified that this 
opprobrious epithet, reflecting harshly upon another gen- 
tleman's pedigree, was used as a term of endearment at 
Virginia City ; indeed, when a denizen of the Comstock 
returned from the Coast he was accosted with a slap on 
the shoulder and the polite inquiry, "How are you old 

of a !" Se iwn e vero, e ben trovato. That is 

what the English lawyer said when I tried to persuade 
him that 'wildcat' was almost a term of financial endear- 
ment. So, to avoid confusion and prevent imposition, as 
they say at Niagara Palls, it may be well to adopt a 
definition more like that of our contemporary at Pres- 
cott. He, of course, cocked an eye at Jerome, where wild- 
cats breed like rabbits. If you apply the epithet 'wild- 
cat' to any of the numerous enterprises having names 
that entwine the words, Great, Copper, Jerome, Verde, 
United, and Extension into a halo of romantic expecta- 
tion, you will be asked indignantly if the United Verde 
Extension was not a 'wildcat' until it was proved a rich 
mine? Was it? It was a risky venture, without ques- 
tion; but it was a sane one, in which the amount of 
money risked was not disproportionate to the possible 
winning. Moreover, the men that subscribed the work- 
ing-capital were able to lose their money without going 
bankrupt ; they risked no more than they could afford to 
lose. The venture was started by an intelligent and ex- 
perienced engineer, who paid for special geological ad- 
vice and proceeded to explore in a scientific way. Even 
the earlier efforts, before Messrs. Douglas and Tener took 
the prospect in hand, were conducted intelligently ; they 
were based on legitimate inferences and their organizers 
made no attempt to collect money "for their personal 
profit" ; the money they raised was spent by experienced 
men in a systematic search for ore and in a locality in 
which ore was likely to be found. It may be said that this 
is wisdom after the event, and indeed the character of a 
wildcat can best be determined by its performance, for 



the motives behind human actions are difficult to prove. 
Unanimity of opinion concerning the various prospect- 
ing enterprises fostered by the astonishing success of the 
P. Y. X. is not to be expected. A few are obviously 
legit imate ventures, a few are equally obviously hopeless, 
if not nefarious, but the larger number cannot be labeled 
with certainty. Those prospecting below the big fault at 
Jerome have a reasonable chance, but, if we may venture 
the opinion, those above are unlikely birds, as unlikely 
as a volant non-ruminating artiodactyle. The absence of 
evidence of ore is used by some of these almost as a favor- 
able argument: "Look at the U. V. X." they say, "that 
had no ore to start with.'" They ignore the geologic 
structure and pin their faith on the happening of a 
miracle. That is not mining, that is ' wildcatting. ' 



More Competency Needed 

The Government 'nitrate plant' at Muscle Shoals, 
Alabama, will begin producing fixed nitrogen from the 
air in the coming month of July. This affords a sense 
of heightened security. At the same time it should cause 
the public to reflect that the same officials that allowed 
themselves to be bamboozled by a group of talkative 
chemists and electricians, still remain in control at Wash- 
ington and are responsible for duties in the serious busi- 
ness of getting this nation ready for war. Less than two 
months ago, nearly a year and a half after Congress had 
appropriated the funds necessary for building a great 
factory to make nitrogen products, a commission of engi- 
neers visited Muscle Shoals and made the final recom- 
mendations that construction be started at once. Perhaps 
the plant will be ready in six months, though we incline 
to doubt it. That would be quick work, which is one 
reason, though not an altogether defensible reason, for 
scepticism. One thing that intensifies the feeling of un- 
certainty is a rumor, which wandered over the wires and 
got into print in the newspapers, to the effect that the 
plant erected by the American Cyanamid Company at 
Sheffield, Alabama, was nearly ready and would soon be 
supplying the needs of the Government. In this con- 
fusion of the facts the public is sure to gain a wrong im- 
pression. Those in authority may claim that a manu- 
facturing establishment is in fact "nearly ready," al- 
though it has just been started, when its completion is 
due in six months, but it is not stating the facts with 
proper regard to their true time relations, to put it as 
mildly as possible. Furthermore, this association of the 
name of the American Cyanamid Company with the 
matter obscures the issue. Either this is a democracy or 
it is not; if it is, then let us run the risks incident to 
democracies by confiding the truth to the people. The 
public, in a democracy, will learn the truth sooner or 
later, and if later the postponment will engender a lack 
of confidence that is like pouring sand into the bearings of 
a dynamo. We understand that the Government, after 
realizing that it confronted the peril of having no ade- 
quate and safe supply of nitrogen products available,

because it had been influenced by men who counseled 
delay under the guise of experimentation, and thereby 
served the cause of the Hohenzollern dynasty, suddenly 
decided to build a big plant, and selected a site that is 
above reproach. It is situated far in the interior ; it is 
capable of easy protection from a military standpoint; 
and it has at command, from the rapids in the Tennessee 
river, a minimum of 680,000 horse-power, which can be 
developed. The American Cyanamid Company then 
came to the rescue with a corps of engineers possessing 
superior knowledge of the details needed for the enter- 
prise. Their accumulated experience, their well-trained 
technical staff, their working drawings, all have been 
placed patriotically at the service of the Government. 
This corporation, therefore, stands among those to whom 
the country owes special gratitude. On the other hand, 
it is important to note that the water development can- 
not possibly be completed within another year, and that 
it is necessary to fall back upon 30,000 horse-power 
obtainable from the Alabama Power Company, and that 
an auxiliary 30,000 horse-power steam-plant will also be 
erected at the foot of the great shoals over which 23 times 
as much energy glides unharnessed and unused, and all 
this because there was no one in authority whose wisdom 
and judgment and sense of duty were large enough to 
protect the interests of the American people. It is no 
light matter to co-ordinate the many activities needful to 
urge forward our preparation effectively. "We do not 
wonder that men fail in the attempt. We are not sur- 
prised at confusion of authority nor at some clogging of 
the wheels of administration. It takes time to find the 
men that can efficiently carry the vital responsibilities of 
war. France swept out ministry after ministry before 
Clemenceau was called to establish a government in 
which confidence could be reposed; England floundered 
through much impressive speech-making to the vigorous 
activity of Lloyd George. Meanwhile we still have 
Daniels and Baker and some others who might at least 
remove the doubt as to their superiority by giving some- 
one else a chance to do better or worse. General Pershing 
has been swift to fit new human metal into his fighting 
machine in Prance in an effort to improve the service. 
It is an instructive object lesson. Incompetence will not 
do on the firing line. What then of incompetence behind 
the firing line ? The world takes it as a matter of course 
that there is efficiency in Germany, while in our own 
country even the man on the street gossips of incom- 
petency. Such a reproach upon American intelligence 
must be effaced, and one essential is to cease being toler- 
ant toward officials and committees that are not achieving 
the results for which they were put in power. The action 
of President Wilson in taking control of the railway 
system was a display of firmness and decision that may 
mark a salutary change in our methods. It would seem 
that many of the war committees need to be re-constituted 
on a basis more consistent with democratic principles. 
The public has reason to distrust the disinterestedness of 
committees when composed of men who are the chief pro- 
ducers of the materials over which they hold authority for 



the Government. The metal-market has been embar- 
rassed for months at a time by failure to declare firm 
policies that looked far enough into the future to admit 
of consistent plans for steady and economical production. 
For example stagnation has afflicted the zinc industry 
because the prices have not been fixed and no indication 
has been given as to the probable requirements of the 
Government. Experience gained from the foreign de- 
mand before we entered the War led to expectations that 
created extraordinary expansion of zinc mining, and now 
the industry is almost paralyzed, while a number of 
properties are maintained in readiness for active opera- 
tion merely in the hope of an early decision by the Gov- 
ernment. Such methods are wasteful of men and money, 
and in the end leave us crippled when the output of the 
mines is urgently needed. The Department of Agri- 
culture has been justly criticized for policies that place 
obstacles in the way of increased food production. On 
account of the extraordinary demand for sulphuric acid 
to make munitions a shortage of fertilizers exists, but no 
organized effort has been made to conserve the wasted 
materials that should be utilized in 'compost heaps', nor 
to encourage efforts to improve the soil without the use 
of super-phosphate, where that is insufficient. Gov- 
ernment financial aid is urgently needed to develop 
additional sulphuric-acid plants in the West where ad- 
vantage might be taken of the vast deposits of phosphate 
rock that now remain unworked. Furthermore, the plan 
to bring under cultivation the great area of 'cut-over' 
lands in the Middle- West and South, in order to obtain 
the benefit of virgin soils, at a time when fertilizers are 
scarce, actually has been discouraged by the Department. 
President Wilbur of Stanford University says that the 
American people have not wakened to the reality of the 
War, but the time has come when they must rouse them- 
selves. They must realize that the committee that fails 
to organize industry, the official that retards the output 
of the necessaries of life, the man that temporizes or 
exalts his selfish interest above that of the common good, 
all these are giving aid to the enemy, and must no longer 
be suffered to stand in the way of effective prosecution of 
the business of preserving our republic. The country 
possesses an abundance of men able to take the places of 
any incompetents and force the work with energy. The 
spirit that should prevail was well expressed in the ad- 
vice given by a committee of the Senate to Secretary 
Baker the other day when he was told to cut red tape and 
order the commanders at the military camps to buy 
clothing for the soldiers in the nearest market. By 
request of the President this advice has been converted 
into a slogan for all the Departments at Washington. 
The object must be to do the things that need to be done 
and to do them swiftly, if we are to win. Efficiency is ex- 
cellent, but, after all, efficiency is mechanical perfection 
and involves routine that takes time to develop. There is 
something superior to efficiency, something for which 
free America has been conspicuous in the past, and in 
which she has not yet lost her cunning. That thing is 
competency, which is the ability to do things with power.

The Rusting of Iron 

The Editor: 

Sir — The article in the Mining and Scientific Press 
for December 8, 1917, on the above subject, contains the 
following statement regarding the Bureau of Mines: 
"The Bureau rejects the electrolytic theory that has 
been so universally accepted, on the ground that pure 
iron, that is to say, the purest iron obtainable, rusts and 
pits as badly, and often worse, than the impure product." 
What the Bureau says in its 1916 Year Book is that 
"many of the actual facts observed . . . are not satis- 
factorily accounted for by the usual interpretation of 
the electrolytic theory. ' ' There is, in reality, nothing in 
the electrolytic theory which does not square with 
"actual facts observed," and the only trouble is with 
the "usual interpretation" of the theory. Exponents of 
the electrolytic theory have never claimed that pure iron 
does not rust, but many manufacturers of pure iron 
have gone too far in claiming immunity to corrosion 
for their product on account of its high purity, forget- 
ting that different polarity, causing electrolytic action, 
may also be caused by distortion or unevenly stressed 
parts in the metal and by accumulations of rust or dirt 
on its surface. These factors are, indeed, quite as im- 
portant in promoting corrosion as impurities contained 
in the metal itself, and this is entirely in accord with 
the electrolytic theory, albeit not with the usual inter- 
pretation thereof. By pure iron is understood certain 
products of the open-hearth processes which are mar- 
keted today and which should more properly be called 
pure steel, for they lack both the graphite contained in 
cast-iron and the slag contained in genuine wrought-iron. 
Cast-iron and wrought-iron are very durable products, 
in spite of the large proportion of graphite and slag 
that are incorporated in the pure iron, but one should 
not be misled into construing this as a contradiction of 
the electrolytic theory, for it is apparent that both the 
graphite and the slag, being in themselves practically 
non-corrodible substances, must, on account of their fine 
distribution, protect the underlying iron from corrosion. 
This protection must increase as more and more of the 
slag and graphite respectively becomes exposed by cor- 
rosion, so that there will be a marked slowing of the 
corrosive effects after years of service. A mistake often 
made is to put commercial wrought-iron under the term 
'pure iron'; while it is pure in a chemical sense, it is 
equally certain that it contains from 5 to 6% of slag 
mechanically mixed with the iron, and, in my opinion, 



it is this very slag that gives it the characteristics that 
distinguish it from pure steel, namely, a tough fibrous 
structure, tremendous resistance to vibration and re- 
peated stresses, and a high factor of immunity to cor- 
rosion.

Recruiting Labor From Gold Mines 

The Editor: 

Sir — S. E. Rau-Boesler's argument concerning the 
ethics of certain engineers and the reflections thereof on 
the profession in general, has aroused deep interest on 
my part, and has brought to mind ideas embracing the 
interrogative : "Would it be consistent for a man, whether 
engineer, metallurgist, or miner, to refuse the acceptance 
of what he considered a better opportunity if such should 
present itself? In fact, do we not all encourage such a 
system by even so small a thing as a business card, and 
by our earnest endeavors to produce results ? Our stock 
in trade is our brains and labor which we sell or lease 
to the highest bidder if said bidder is financially able to 
cover his bid, as we must figure on covering the initial 
plant, our brains, together with depreciation at an early 
date in life. Allow me to suggest in this connection a 
method of combating the Inspiration system of pro- 
curing labor. Would it not be much better to visit with 
the miners whom Mr. Arnold had employed, wish them 
good luck, a pleasant journey, and incidentally mention 
that your company stood ready to pay their return fare 
and that of any other good men they could secure while 
working for the Inspiration, at the same time sticking 
up some posters showing the miner's wage at each camp, 
the methods of working men, the living conditions, and 
general surroundings. With the balance in favor of the 
garden, I am sure such a procedure would bring results.

The Need for Gold 

The Editor: 

Sir — Under your issue of December 1, I notice an 
article on this subject by Lester S. Grant. I would like 
to make a few comments on same, though they are rather 
rusty, as I have not been in South America since 1910 
and 1911, where I came in contact with a good many 
drummers from various parts of North America and

Europe, who were selling goods payable in Peruvian 
soles, which is a facsimile of the English pound sterling, 
the only Government in South America that has pro- 
hibited the issue of paper money. 

In the larger cities of Chile, to wit, Valparaiso and 
Santiago, landlords some fifteen years previously rented 
their premises at approximately $300 per store, payable 
in Chilean money, which at that time, if my memory is 
correct, had depreciated to about 25c. on the dollar, the 
depreciation of which bankrupted a great many land- 
lords; in both Chile and Argentine, where paper money 
is exclusively used (paper money in Chile being worth 
then about 25c. on the dollar and in Argentine about 
50c. on the dollar) there being no gold in circulation, 
restaurants omitted from their bills of fare the price of 
ham and eggs and everything else, and the price paid 
was the quotation of paper money at its value for that 
day. 

As Mr. Grant says, we may have a gold and silver 
stock sufficient for what we think is necessary for this 
year and possibly the next, but if gold is smuggled out 
of our country, as it has been in South American coun- 
tries, with the exception of Peru, our paper money will 
have no more value than Confederate money, which was 
backed by no gold reserve at all. Without a plentiful 
supply of gold and silver our paper money is worth 
no more than yesterday's newspapers which kindle to- 
morrow's fires. _ „ _

Oil in Flotation 

The Editor : 

Sir — I have read with interest statements by your- 
self and by others that oil was not necessary for floating 
mineral particles, yet so far as I have read no one has 
stated what these reagents are or what results were 
obtained by their use. In a recent issue of your paper, 
Mr. Sehwarz states that he is successfully floating lead 
from zinc, making nearly as complete a separation as 
that of any other mineral floated from its gangue, yet 
he neither states what reagents he uses nor the results. I 
am treating a high-grade lead-zinc ore, and the best re- 
sults I have obtained are about 50% lead and 24% zinc 
by the use of eucalyptus oil. The feed is about 3% lead 
and 20% zinc; after selective flotation of lead and flota- 
tion of zinc, the tailing contains trace of lead and under 
2% zinc. Will some of your writers kindly give figures 
of their results on the selective flotation of lead? 



MlLLMAN. 



Los Angeles, December 29, 1917. 



[We have referred editorially more than once to the 
use of nitro-naphthalene and alpha-naphthylamine, pat- 
ented by H. P. Corliss, as a frothing-agent instead of 
oil. Naphthalene is the moth-ball of commerce. Both the 
above-mentioned reagents are derivatives from naph- 
thalene, which, in turn, is the creosote fraction from the 



distillation of coal-tar, itself a by-product of the coke- 
oven. The naphthalene is nitrated with nitric acid, the 
resulting alpha nitro-naphthalene is then treated with 
hydrochloric acid and iron shaving, which reduces the 
nitro-compound to the amine derivative, producing the 
alpha naphthylamine, which is the frothing-agent — 
C 10 H 7 NH 2 — used in flotation. Its solubility is in the 
ratio of 1000 : 1 in cold water and 600 : 1 at 50° C. From 
i to i pound per ton of ore suffices to produce a highly 
efficient froth. In regard to the selective flotation of 
lead, our correspondent is referred to the chapter on 
'Differential Flotation' by O. C. Ralston in the book en- 
titled 'Flotation', published recently. — Editor.] 



Misfires 

The Editor: 

Sir — In reply to Mr. Harrington's article on misfires, 
in the December 1 issue of your paper, will say that if 
proper care is given to trimming the fuse-end that is 
used for the cap, a large percentage of misses will be 
avoided. I have been employed at the Tamarack mine, 
at this place, where there has been considerable trouble 
with misses ; the miners say it is the caps, others say the 
fuse ; I found it was a dull knife used and fuse cut square 
across; also carelessness in inserting the fuse into the 
cap. I have taken caps where the fuse had burned to the 
cap and cut new fuse properly aud exploded the cap. I 
have noticed that the man who makes the primers gen- 
erally tries to see how fast he can work, and cuts his fuse 
with a dull instrument square across, and nearly always 
there is a little gutta percha drawn across the powder; 
he then forces the cap on, and crimps; the result is a 
few misses. When I want to be sure of my round, I 
try to cut my fuse with a sharp knife diagonal with the 
fuse, make a clean cut, and when inserted in the cap I 
see that, it does not jam but goes in free — do not crowd 
it hard against the powder, then crimp. For wet holes 
let him use P & B paint. You can crimp your cap on 
ever so well, but if you don't cut your fuse right and 
with care you must expect misses. Let your contributor 
try my scheme, and I am sure he will get results, as I 
have used this method where others fail. If he gets re- 
sults from my method, then I will feel re-paid for this 
letter. 



Henry Hoard. 



Sunset, Idaho, December 12, 1917. 



[Our correspondent has hit upon a probable cause of 
the trouble mentioned by Mr. Harrington. We had pre- 
viously made a similar suggestion in an editorial article 
entitled 'Blasting Troubles' in our issue of December 8. 
We called attention to the pinching of the fuse in cut- 
ting with a defective instrument of the type commonly 
supplied in w-hich a fuse-cutter and crimper are com- 
bined in the same tool. The dull knife, as Mr. Hoard 
points out, would have a like effect. The dragging of 
the outer layer of gutta percha across the powder-core is 
a fertile cause of failure to explode the cap. In general 
we advise the square cut. — Editor.]

BOGOMOLOVSKY MINES: GENERAL VIEW AND WORKMEN'S HOUSES 



The Bogomolovsky Copper Mines, Russia 



By N. T. TRUSCHKOFF 



These mines are in a pyrite belt on the eastern slope 
of the Ural mountains, formerly worked for gold until 
copper pyrite was found below the gossan. 

The Bogomolovsky mines belong to the Bogoslovsk 
Mining Co. ; they are situated 10 miles north-east of the 
station Goroblagodatskaya on the Perm & Gornozavodsk 
railroad in the Verhotursk district, department of Perm ; 
they also lie six and one-half miles south-east of the sta- 
tion Verknaya on the Bogoslovsk railroad, which runs to 
the Bogoslovsk company's Nadejdensky iron works and 
connects the Perm with Bogoslovsk railroads, the Nadej- 
densky works being the terminal of the Bogoslovsk 
narrow-gauge line. A standard-gauge line is under con- 
struction now to connect the Bogomolovsk mines with 
Verknaya ; this branch railroad was expected to be ready 
by the end of the current year. Eight and one-half 
miles south-west of the mines is the Government's Kushva 
iron works with its famous Mount Blagodat iron ore 
deposit ; 10 miles south of the Kushva begins the Nijny 
Tagil — one of the largest and oldest mining districts in 
the Ural region, producing iron, copper, platinum, and 
gold. The accompanying map shows the relative posi- 
tion of the mines to the neighboring country. All the 
surface near the Bogomolovsky mines is covered by 
forest; the district is intersected by many small rivers, 
whose gravels have been worked by local diggers 
('starateli') for gold and platinum. Bogomolovsky, how- 
ever, promises to become far more important for its cop- 
per. Pour small rivers are on the strike of the ore-bear- 
ing zone ; going north they are Salda, its tributary 
Kushika, and Tva, with its tributary Kljuchovka, the 
Salda having enough water for a metallurgical plant. 
Two groups of mines were bought by the Bogoslovsk Min- 
ing Co. from Mr. Bogomoloff's successors: a western 



group, consisting of two claims, Plastorazdelny and 
Verinsky, marked on the map, and an eastern group, ad- 
joining the first one and including 21 claims, which repre- 
sented the main gold-bearing area at the time of Mr. 
Bogomoloff's operations. Only the western group is 
being developed now, the prospecting work on the eastern 
group being barely started. 

The copper-bearing zone trends north-south and in- 
cludes the western group of two claims, to which ad- 
join four new Bogoslovsky claims. South of the Plastor- 
azdelny claim are the Ponizovkin gold mines with a pyrite 
deposit, and two similar deposits belonging to Ushkoff 
& Co., producing pyrite for large sulphuric-acid plants 
and dye works on the Kama and Volga rivers, of eastern 
and middle Kussia. North of the Verinsky claim are the 
so-called old and new Levinsky mines near the Klju- 
chovka river, on the Verkne Turinsk peasant lands, 3000 
dessjatins (each 117,600 sq. ft.) of which are leased by 
the company under a special agreement. Farther north 
on Government land, up to the Emech river, intensive 
prospecting is in progress on all the ground controlled 
by the company; altogether an area more than 15 miles 
long by 1 mile wide belongs to the Bogoslovsk Mining 
Co. along the general strike of the ore-bearing zone. A 
subsidiary company is to be formed to operate this prop- 
erty. The country-rock is granite and 'keratophyre'; 
the granite is not productive where massive; the kera- 
tophyre represents, according to the Bogoslovsk Geolog- 
ical Survey, an effusive soda-felsite porphyry, the main 
constituents of which are albite and oligoclase, seldom 
hornblende. The rocks forming the larger part of the 
mineralized area are altered keratophyre and its deriva- 
tives, metamorphic schists, more or less chloritic, which 
vary in color, being dark-gray, red, yellow, and white.

This belt of metamorphosed mineral-bearing schist ex- 
tends N. 15° W. and is about three-quarters of a mile 
wide. Copper-bearing pyrite occurs in the form of lenses 
in the highly altered argillaceous schist, which near the 
contact is nearly white. A gossan cap, about 60 ft. thick, 
is always found on the top of the ore; the outcrop is 
under the soil and debris, 3 to 10 ft. thick, the country 
being swampy and thickly covered by forest and brush. 
The schist belt is intersected by sev- 
eral porphyry dikes, which have, as 
far as we know now, no influence on 
the mineralization. The mineralized 
belt is on the line of other deposits of 
cepper-pyrite on the eastern slope of 
the Urals, being the continuation of 
those at Kyshtim, Syssert, and Kal- 
ata. Pyrite was lately found on the 
same strike on the Vinnovka river in 
the adjacent Nijne-Tagilsk district. 

Pour diamond-drills are working 
continuously along the belt at places 
where gossan has been uncovered by 
prospecting pits. The first lens of 
cupriferous pyrite was found in 1915, 
on the boundary of the Verinsky and 
Bogoslovsky No. 3 claims by a pit that 
struck the gossan several feet below 
the surface. Ten diamond-drill holes 
were set along the strike of the cap as 
ascertained by pits and cut the vein 
at vertical depths ranging from 95 to 
735 ft. All the holes incline 45° 
south-west (three are 52° and one 60° 
south-west). In the hanging wall the 
incline depth of the holes is from 328 
to 1297 ft., the distance between the 
holes averaging 164 ft. The average 
width of the lens down to the level, at 
686 ft., is 50 ft. The lens strikes 
N. 24° W. and dips N. 70° E. The 
ore-reserve of 3,400,000 short tons, to 
a depth of 660 ft., will average 3.6% 
copper. The ore persists in depth, so 
far as known. Several more drill- 
holes have been started to cut the lens 
at a greater depth. The average assay of ore from the 
drill-holes shows 40% S, 10% Si0 2 , 40% Fe, 1% 
CaO, 0.75% Cu (from traces to 12%). The depth of 
oxidation is 60 ft. A second lens has been uncovered 
on the Novo-Levinsky claim, along the same strike; two 
drill-holes cut pyrite containing copper; drilling is pro- 
gressing and according to data available this lens is 
similar to the first one both in size and value. The ore- 
bearing belt of schist is being systematically prospected 
along the strike by pits 4| by 3 ft., inside timbers ; the 
lines (across the strike) of the pits are 700 ft. apart, the 
distance between pits on each line being 70 ft. Pits are 
sunk until they strike original rock or gossan ; if the lat- 
ter, the pit is sunk deeper and a cross-cut made. Stripping 



overburden is started at the outcrop of the second lens 
where the gossan is shallow. Development work was 
started in 1916. One vertical three-compartment shaft, 
the No. 7 Bogoslovsky, 14 by 7 ft. inside timber, was 
sunk in the hanging wall of the first lens and has cut the 
vein in a cross-cut at 105 ft., where a station is established 
and drifts started north and south. The sinking of this 
shaft is to be continued. Several other shafts, 9 ft. 4 in. 




MAP OF PAST OF UBAL REGION 



by 4 ft. 8 in. inside timber, have been sunk to the same 
depth as the main shaft along the line of gossan at the 
distance of 150 to 200 ft. for ventilation and for lowering 
timber. Two assays of the gossan, cut when sinking the 
shaft, 28 and 35 ft. from the surface, respectively, gave 
17.82 to 33.83% iron, 0.05 to 0.10% sulphur, $3.90 to 
$10.28 gold per short ton. The gossan may be suitable 
for cyanidation. Assays of ore on the 105-ft. level (40 
ft. below the gossan) gave from 33.50 to 43.88% sulphur, 
9.24 to 26.89% silica, 27.12 to 38.02% iron, traces to 
0.43% zinc, 4.6 to 12.65% copper. A sample of 976 short 
tons of bulk ore taken between the 70-ft. and 105-ft. levels 
was smelted at the Bogoslovsky copper smelter last sum- 
mer and yielded 7J% copper.

Owing to the present politieal conditions only pros- 
pecting work and small development work are possible 
now. Ingersoll-Rand hammer-drills are mostly Ofled in 
driving and sinking. The driving is done by contract at 
a price of 130 rubles per cubic sagene ($65 per 343 cu. 
ft., or about $9.30 per linear foot of 7 by 7 ft. drift) 
timbering and explosives included; stoping costs R75 
per cubic sagene (a sagene is 7 ft.). An Eclair (Belgian 
make) 40-hp. belt-driven compressor delivering 300 cu. 
ft. free air per minute is working now, and an Ingersoll- 
Rand Imperial type XB2 compressor, of 1051 cu. ft. per 
minute capacity, has been ordered. 

A village for the employees and workmen was under 
construction during the summer. Three-shift work of 
eight hours is carried on underground. The average 
earnings for Russian miners in the month of May last 
were: Drillers R3.77 ($1.89 at pre-war exchange) 
per 8-hour shift, timbermen R4.64, trammers 4.50, day- 
laborers underground 3.14, surface 2.35, smiths 5.43, 
helpers 4.50, fitters 3.50 to 5.85. Besides Russians, who 
number only 50, Chinese and war-prisoners, up to 150, 
are employed, mostly on surface. War-prisoners under- 
ground receive R2 to 2.50 per shift on contract and R2 
on day's pay. The average Chinese wages are R2 daily. 

A modern reduction-plant is to be erected near the 
mines, with a sulphuric-acid plant. The ore now pro- 
duced is transported to the Bogoslovsk works, where it 
is smelted in two water- jacketed blast-furnaces, 228 by 
42 in., and 84 by 36 in. at the tuyeres, together with 
local ore from the Toorinsky copper mines. 

Ventilation pit No. 203 and shaft No. 7 are poor in 
sulphur (7 to 12% S). The Bogoslovsk smelter has 
extra capacity for treating 60,000 tons of pyritic ore per 
annum, besides local ore. The addition of Bogomolovsk 
pyrite to the charge, owing to its sulphur, reduces the 
percentage of coke required and results in a considerable 
decrease of cost. 

Conditions in Russia at the present are unfavorable for 
starting any large mining enterprise; but after the end 
of the "War there will be great possibilities for an ex- 
tensive development of the mineral regions. The present 
tangled situation will not last long. The defeat of the 
Bolsheviki, who emporarily control Petrograd and a few 
other industrial centres where the workmen are swayed 
by radical socialistic sentiments, is certain. The Bol- 
sheviki represent Russia no more than the I. W. W. repre- 
sent the United States. The heart of Russia is sound, 
and the mass of the people is against Germany. The 
Germans may make peace with Lenine, Trotzky, and 
other traitors and German agents from the Smolny 
Institute, but they can never make peace with real 
Russia. The extreme socialistic parties have no follow- 
ing among the bulk of the population. The more moder- 
ate parties and all the reasonable soldiers not spoiled by 
German propaganda are consolidating with the middle 
classes. The election for a constitutional assembly will 
help in the establishment of order. The accompanying 
photographs show the No. 1 shaft as it appears at the 
present time.

Wolframite in South China 



A recent discovery of wolframite in marketable quan- 
tities has been made in Kwangtung province. Following 
the discovery the natives, and even the official deputies, 
mistook it for manganese or iron ore, until the high prices 
offered raised a suspicion that it must contain something 
different from the common metals. The Japanese first 
learned of the value of the so-called 'iron ore' in Hunan 
province, and offered about 27e. Mexican, or 17c. gold, 
per pound for it. Other buyers learned of the bargain, 
and offered better prices. Now the average ore com- 
mands about $32 gold per 100 lb. at Canton. Much of 
the ore comes from Chengehow, adjacent to the border of 
Kwangtung province. It is transported on men's backs 
to Ping Shek, a distance of 60 miles. From here it is 
carried in junks down the North river to Shiuehow, 80 
miles, whence it is brought to Canton over the Yueh-Han 
railway. Haifong district has been reported to produce 
wolfram ore, but no actual mining has begun. Kwangsi 
province also is said to produce it. A Chinese company, 
while prospecting for antimony some time ago in 
Kwangsi, found small seams of wolfram in the Hoehi 
district, 120 miles north-west of Liuchowfu. The ore 
occurs in hard quartz, and the cost of mining is excessive.

Buying Combinations in the Metal Market 



BY THE FEDERAL TRADE COMMISSION 



Close Inter-relation of Producers, Traders, and 

Larger Consumers 

•Before the War the control of the world's metal 
market was in the hands of a group of German metal- 
traders, who are primarily engaged in buying metal, or 
in acting as selling agents for producers, and in selling 
it to European and Asiatic consumers. From the stand- 
point of the American metal-producers they are to be 
regarded primarily in the light of buyers, although in a 
broader sense they might well be defined as traders, since 
they both buy and sell. The description of their activi- 
ties here given is from the American point of view. In 
a general way, it may be said that in Germany is cen- 
tred the control over many of the largest producers of 
metals, while the London Metal Exchange and silver 
'fixing board' exercise and control the price-fixing power 
to such a degree that London has become the inter- 
national market for almost all metals, and that London 
metal quotations set the standard for the metal business 
the world over. 

With regard to the fixing of prices in the metal market 
the national and international metal cartels and syndi- 
cates are of primary importance. The metal trade is 
notable for the extraordinary degree in which it has 
been concentrated in the leading metal-producing and 
metal-consuming countries of the world. A compara- 
tively small number of firms control this trade the world 
over, and most of them are more or less closely inter- 
related. These combines fix the price and regulate the 
production of the metals and metal products controlled 
by them in their respective territories, and thus indi- 
rectly have an important bearing on the price question 
as it affects the metal market. The part played by the 
banks in the control of the metal business is largely re- 
sponsible for the internationalization of the metal trade. 
Through syndicate agreements, price cartels, and inter- 
locking directorates, certain banks of England, Germany, 
Holland, Switzerland, and Belgium have managed to 
secure control over the largest metal plants and metal- 
selling agencies of the world. 

Another interesting feature of the metal combines con- 
sists in the fact that a number of large and important 
industries are dependent upon the metal trade for their 
supply of raw materials. Among these the electrical and 
the chemical industries rank foremost. Almost half of 
the total copper production is used for electrical pur- 
poses. 

*Taken verbatim from 'Report on Co-operation in American 
Export Trade'; Federal Trade Commission; June 30, 1916. 



This close inter-dependence as well as manifold other 
common interests have been instrumental in bringing 
about a far-reaching system of co-operation among the 
leading metal firms and industrial cartels and syndicates. 
Thus the Metallgesellschaft of Frankfurt before the War 
was the common selling agency for the French Aluminum 
Syndicate, and it serves in a similar capacity, together 
with Beer, Sondheimer & Co. of Frankfurt, and Aron 
Hirsch und Sohn, of Halberstadt, for the German Zinc 
Syndicate. Aron Hirsh und Sohn are members of the 
German Copper Sheet Syndicate and of the Combine of 
German Copper Wire Works. The Deutsche Gold- und 
Silberscheideanstalt is closely allied with the chemical 
industry and is a member of several chemical cartels. In 
1900 it organized and managed a syndicate of calcium- 
carbide manufacturers. In the latter industry the 
Siemens-Sehuekert concern, one of the groups that con- 
trol the German electrical business, is heavily interested. 
By means of the Metallurgische Gesellschaft the Merton 
interests, which are the chief factor in the metal-buying 
combination, acquired large holdings in the German pot- 
ash industry through the Gewerkschaft Rastenberg. On 
the chart opposite page 366 [on page 87 of this issue] 
the number and extent of these inter-relations is pre- 
sented. 

Through banks, holding companies, affiliations with 
syndicates and cartels, interlocking directorates, joint- 
share holdings, and other means of inter-relation, a 
world-wide ramification has taken place in the metal 
trade. 

. The following examples will illustrate how some of the 
more important metal concerns are allied through inter- 
locking directorates. Of the Merton family, of Frank- 
furt and London, five members are directors in most of 
the companies controlled by or affiliated with the Metall- 
bank of Frankfurt ; R. Merton is connected with the 
Merton Metallurgical Co., London, the American Metal 
Co., Ltd., the Australian Metal Co., Ltd., and the Com- 
pagnie des Minerals de Liege. Walter Merton is a di- 
rector of the Metallbank & Metallurgische Gesellschaft, 
Frankfurt a. M. ; the Metallgesellschaft, Frankfurt a. M., 
and of the Merton Metallurgical Co., London. H. 
Gardner is on the board of directors of Henry B. Merton 
& Co., the Australian Metal Co., the Merton Metal- 
lurgical Co., the Mines de Pierrefitte, and Williams, 
Foster & Co. A. Ladenburg is a director of the Metall- 
bank and of the Schweizerische Gesellschaft fur Metall- 
werke. Walter vom Rath is a director of the Metallbank, 
the Metallgesellschaft, the Lahmeyer electrical concern, 
the Hochster Dye Works, and the Allgemeine Elec- 
trizitats Gesellschaft.

The Frankfurt metal firms are also connected with 
some of the leading German banks through interlocking 
directorates, viz., the Hirsch concern with the Deutsche 
bank; the Deutsche Gold- und Silberscheideanstalt with 
the Metallbank, Frankfurt a. M., and the Oberschleisische 
Zinkhiitten A. G., Kattowitz, with the Nationalbank fur 
Deutschland. 

Silver. According to the statement of a large Ameri- 
can concern, which exports about seven-tenths of its sil- 
ver output to London, the silver trade of the world is 
dominated by the London Metal Exchange : 

The price of silver is fixed in London by what is 
termed publicly the 'fixing board,' which consists of four 
banking or brokerage houses dealing in silver and East- 
ern exchange. This board of four representatives meets 
at a quarter past two every afternoon. This permits 
prices to be made in New York at the opening of business 
here, on account of the difference in time. Since virtu- 
ally the entire silver business of London is in connection 
with exportations from the United States, it will be seen 
that the meeting-time in London is after the members 
of the fixing board know the full receipts and demands 
in London, but before business opens in New York. All 
silver in London is sold through these members of the fix- 
ing board. The distribution of silver in London, as stated 
above, is approximately 75% for shipment to the East, 
which is sold entirely to Eastern banking representatives, 
both English and continental, for coinage purposes, and, 
to a minor extent, to the manufacturers of silver. The 
Eastern banks and the Government representatives will 
not buy through anyone except members of the fixing 
board, and at the fixed prices, because if they do other- 
wise they take a responsibility which they do not seem 
to be willing to take. In fact, if they should buy in any 
quantity from other parties, the fixing board would 
probably fix a price that would make their purchase 
open to criticism. These four brokers, therefore, have 
the ability, and exercise it, to absolutely fix every day 
the price at which the entire product of the mines of 
the United States in silver has to be sold. 

This fixing board has, however, a much greater power 
than that covered by the actual transactions in fine silver, 
for the reason that the commerce of the East, India, and 
the Straits Settlements and China is expressed in silver; 
in other words, the entire exchange transactions of Lon- 
don, covering the entire commerce between the continent 
of Europe and India, is expressed in silver values, and 
the price of silver is the price of exchange. These ex- 
change transactions are at least ten times as great as the 
total value of silver purchased and sold in London. The 
great Eastern banks are the great buyers not only of 
silver for export to the East, but also of the exchange 
covering the commerce with the Hast. The silver value 
of the American mines is dominated by four brokers, 
designated as a fixing board. 

Copper. According to the statement of a large Ameri- 
can concern, which exports about six-tenths of its copper 
output to Europe, prices established by the London Metal 
Exchange determined to a large extent prices of copper 



at any port in Europe. Since the present War the Brit- 
ish director of materials promulgated the following regu- 
lations in relation to sales of copper : 

1. Orders up to and not exceeding 50 tons may be 
placed in the*usual way, without reference to the Min- 
ister of Munitions. 

2. No orders for best selected or electrolytic brands of 
copper shall be placed at prices exceeding £100 per ton, 
without first consulting the director of materials. 

Commenting on the effects of this order, the American 
concern said : 

This action was taken on January 5 last. The immedi- 
ate effect of this action with reference to copper was to 
stop the buying. The British Government, stating that 
they were acting also for their allies, Russia, France, and 
Italy, had previously negotiated large purchases of cop- 
per in this country for delivery spread out over a year. 
A very large proportion of the amount of copper ex- 
ported is now being purchased by Governments, all act- 
ing in conjunction with one another, and is being dis- 
tributed by these Governments to their manufacturers. 
Furthermore, we know that our sales of copper, made to 
the largest consumer of copper in France, are being dis- 
tributed by them to their normal competitors at the pres- 
ent time. 

On the subject of the purchase of copper by German 
buyers before the War, the American concern stated: 
The German consumption was such a large proportion 
of the total amount of copper exported that German buy- 
ers had more influence in fixing the value of copper than 
the English buyers. It was very evident to this company 
that the buyers of Germany at least worked as a unit. 
They would repeatedly remain out of the market for 
weeks at a time and would not accept any offer made, 
during which time the American sellers would accumu- 
late such amounts of copper that they would be obliged 
to reduce their offers. The German buyer would wait 
until the offers were reduced sufficiently and then would 
come in again as the unit and buy in very large quanti- 
ties. This process of buying at the lower and refusing to 
buy at the higher price, which was naturally stimulated 
by their very heavy buying at the low price, resulted in 
the average price at which the American buyer, who 
bought more regularly and was more inclined to buy at 
the panic high prices, could buy. The result is, so far as 
the sales of this company are concerned, and we believe 
that there is a similar condition on the part of other sell- 
ers of copper for exportation, the average export price is 
considerably lower than the average price obtained from 
the American consumers. The difference arises entirely 
from the selection as to the time of buying and not from 
the holding of a price at any one time by this company 
to American consumers above that offered to consumers 
abroad. 

On conditions in the German market since the War 
began, the American concern said: In Germany at the 
beginning of the War a combination of all the large 
German consumers and metal merchants was made, 
known as the Kriegsmetall Gesellschaft. This combina-

tion has assembled and distributed the copper supply of 
the country. This is recognized as an incident of the 
War, but we are now informed it is proposed to continue 
this combination after the War is over. It would thor- 
oughly and effectively combine all of the large tonnage 
of copper which has heretofore been purchased in this 
country, and place the American producers at a tremen- 
dous disadvantage. In Germany there are interlocking 
directorates, with large financial interests holding shares 
in the companies that are largest consumers of copper, 
which enables the management of the respective com- 
panies to act jointly in purchasing their requirements of 
copper in this country. The United States has hereto- 
fore supplied most of the copper used in Germany, and 
Germany has been the largest consumer in Europe. 

The bearing of the conditions existing in the European 
markets on the copper industry in the United States may 
be understood when it is realized that the United States 
produces about 56% of the world's supply of copper, and 
exports about three-quarters of its annual production. 
In the year ending June 30, 1914, it exported 975,000,000 
lb., valued at $145,000,000, seven-eighths of the exports 
being in the form of pigs, ingots, and bars. Of the total 
quantity of exports, 96% went to Europe. Germany 
took one-third of the exports to Europe. In addition to 
the quantity purchased by the great German metal- 
buying combinations, headed by the Metallgesellschaft, 
many of the large consumers of copper acted in concert 
in their purchases, through their cartel arrangements. 
According to one large American copper-producing com- 
pany, they had reports from their Berlin agent of the 
existence of more than 50 combinations of copper-con- 
suming companies for the regulation of prices, distribu- 
tion of territory, and for concerted action in buying. 
According to John D. Ryan, of the Amalgamated Copper 
Co., European buyers, from 1903 to 1913, because of a 
buying combination, paid 83/100 of a cent per pound less 
for copper delivered abroad than domestic buyers for 
copper delivered at New York. 

Znsrc. The German zinc syndicate (Zinkhiittenver- 
band) was organized in February 1909 with a capitaliza- 
tion of 2,000,000 marks for the apportionment of the out- 
put and for the fixing of the sales prices of zinc. The 
active organizers of the syndicate were the Metallbank 
of Frankfurt, controlled by the Merton interests; the 
Frankfurt metal-selling and holding company, Beer, 
Sondhehner & Co., which, through the Tellus joint-stock 
company, controls over a dozen metal and chemical con- 
cerns ; and the firm of Aron Hirsch und Sohn, at Halber- 
stadt. Both the latter metal-dealers established their 
own new zinc works at the moment of the organization of 
the German zinc syndicate. 

Seven zinc works of Silesia and six zinc concerns of 
the Rhenish-Westphalian region at once joined the syndi- 
cate. The Metallbank, Beer, Sondheimer & Co., and 
Aron Hirsch und Sohn were made the exclusive selling 
agencies of the syndicate and the agreement was to con- 
tinue for three years. Only one important concern, the 
Georg von Giesches Erben, retained its right to deal 



directly with the consumers, under the condition, how- 
ever, that it should comply with the price-lists of the 
syndicate. 

Immediately upon the organization of the German 
zinc syndicatt (Zinkhuttenverband) an agreement was 
made with the Austrian and Belgian producers, of which 
the Vieille Montagne had works in Belgium, France, 
Algeria, Germany, Italy, England, Sweden, and Spain, 
and agencies in Tunis, America (United States), Japan, 
and Turkey. A Dutch concern (Zincs de la Campine) 
also joined the syndicate. The syndicate embraced alto- 
gether 18 firms. Ten Belgian and some French works 
formed another syndicate ; so did six English works. 
During the same year, 1909, the competition of the 
United States concerns drove all these three groups to- 
gether into the International Zinc Syndicate (Inter- 
nationaler Zinkhuttenverband). 

The International Zinc Syndicate was continued on 
November 10, 1910, up to April 1914. The syndicate 
agreement left the English and the French works free 
to fix their prices, and it is said that in some cases they 
underbid the German works. The agreement also pro- 
vided that in case the reserve had reached 50,000 tons 
and the zinc prices in London had gone below £23 per 
ton the output should be reduced. Before the outbreak 
of the present War a 20% reduction of output was 
ordered. 

The price changes made by the German Zinkhutten- 
verband always correspond to those made by the Inter- 
national Zinc Syndicate for the London Metal Exchange, 
which, it is said, gets its instructions from the Metallbank 
of Frankfurt, that is, from the combined Merton, Beer, 
Sondheimer & Co., and Aron Hirsch und Sohn interests. 
The zinc and other metal dealers of Germany act in 
unison as purchasers from any foreign concern. 

By the end of 1912 the German Zinkhuttenverband 
controlled one-half of the world's output of zinc, and 
three-fourths of the European output. The Interna- 
tional Zinc Syndicate regulates output only, while the 
German syndicate (Zinkhuttenverband) regulates both 
output and prices within its sphere. The actual price 
regulation is carried out by the Kolner Zinkhuttenver- 
band, which appears to be but a subdivision of the Ger- 
man syndicate (Zinkhuttenverband). It must be re- 
membered that the German syndicate has two distribut- 
ing agencies — one in Cologne and the other in Kattowitz 
(Silesia). The published price quotations, however, do 
not represent strict sales prices, but form only the basic 
price on which the actual sales prices are computed. 

Lead. In 1908 an agreement was reached between 
German lead works and Australian lead-mine owners as 
regards prices and apportionment of markets. The com- 
petition of Spain and of the United States compelled the 
lead interests to organize in the spring of 1909 the In- 
ternational Lead Convention. The Australian Broken 
Hill mines, the American Smelting & Refining Co., some 
Spanish and some Mexican mines, the Usines des Desar- 
gentation of Antwerp, and the German Bleihiitte 'Call' 
formed a common sales agency under the leadership of

Am mini u. Close relations exist between the Mi 1 on 
concern and the aluminum industry, especially the 

11 Aluminum Syndicate, and through the b 
with the International Aluminum ('arid formed in 1912. 
The Metallgesellschafl of Frankfurt was instrumental in 
organizing the French Aluminum Syndicate in November 
1910, and since then it lias Berved in the capacity of its 
common selling agency, which handles the entire export 
of the French Aluminum Syndicate. The following com- 
panies are members of the French syndicate: Societe* 
Eleetro-Metallurgique Francaise ('Froges'), Compaguie 
des Produits Chimiques d'Alais et de la Camargne 
('Salindres'), Societe des Forces Motrices et Usines de 
l'Arve, Societe des Produits Electro-Chimiques et Metal- 
lurgiques des Pyrenees. Societe Eleetro-Metallurgique du 
Sud-Est. and the 'Societe d'Electrochimie. 

Several aluminum factories also manufacture calcium 
carbide, and in 1900 the Deutsche Gold- und Silber- 
scheideanstalt organized and managed a syndicate of 
calcium-carbide producers, which was dissolved in the 
following year. An international carbide syndicate was 
formed in 1910 for a period of 10 years, of which all of 
the 58 carbide factories of Europe (in France, Switzer- 
land, Germany, England, Austria, Norway, and Sweden) 
became members. 

The electrical industry has for many years been closely 
connected with the manufacture of calcium carbide, 
especially the Schuckert interests. 

In October 1910 the following German producers or- 
ganized the German Aluminum Purchasing Association 
(Deutsche Aluminum Einkaufsvereinigung) : 

Fried. Krupp-Grusonwerk, A. G. 

Julius & August Erbsloh. 

Karl Berg in Eveking. 

Vereinigte Deutsche Nickelwerke in Schwerte. 

Th. Goldsehmidt in Essen. 

Basse & Selve, Liidenscheid. 

Through this purchasing combine the metal industry 
was connected with the Krupp concern, the great steel, 
ship-building, ordnance, and munition manufacturers, 
on the one hand, and with the copper and brass industry 
on the other. Basse is one of the directors of the Luden- 
scheider Metallwerke, A. G.. Vormals Jul. Fischer und 
Basse, a large consumer of metals, and a producer of fine 
machinery and various articles from copper, brass, and 
new silver. American metal exporters state that the 
Liidenscheider Metallwerke, A. G., are also closely con- 
nected with the Metallbank of Frankfurt. 

The German Metal-Buying Combination 

There are three main groups of interests which to- 
gether dominate the German metal market. They are 
the group identified with the Merton family, including 
the Metall Gesellschaft, the Metallbank und Metallur- 
gisehe Gesellschaft, and the Deutsche Gold- und Silber- 
scheideanstalt, the group identified with Beer, Sond- 
Tieimer & Co., and the group identified with Aron Hirsch 



mill Sohn, The principal relationships of these three 

groups are shown on the chart.

LURGISCHJ Gl -i 1 1 31 11 in, LND II. K. MERTON & Co., LTD. 

The Metallgesellschaft, A. <;., Frankfurt a. M., was 
founded in L881 bj Wilhelm Merton. It took over the 
metal business of Ins tjiamlfatlicr Philipp Abraham 
Cohen. Wilhelm Merton was the son of the senior mem- 
ber of the firm of Henry It. Merton & Co. of London. 
When II. Et. Merlon started in business, P. A. Cohen sup- 
plied part of the capital, conversely, later on, II. K. 
Merton'and his brothers Zachary and Emile, who had 
later become associated with him, also had a proprietary 
interest in the Cohen concern. When the two concerns 
were formed into limited companies these interests were 
capitalized in the form of shares in H. R. Merton & Co., 
Ltd., and in the Metallgesellschaft, A. G., Frankfurt a. 
M. In 1878 the London and the Frankfurt interests had 
already joined in the foundation of the American Metal 
Co. As a result of the predominance of the influence of 
the Merton family in these three companies, they have 
been generally known as the 'Merton concern.' 

For the purpose of attracting outside capital, and in 
order to distribute the risk entailed by large investments, 
participating and financing companies were formed. 
The first step in this direction was that the Frankfurt, 
London, and New York firms turned over to separate 
holding companies their interests in mines and smelting 
plants which they had acquired in the course of time. 
In this way, in 1897, there was formed, as a subsidiary 
company associated with the Metallgesellschaft, the 
Metallurgische Gesellschaft, Frankfurt a. M. (capital 
6,000,000 marks) ; in 1907, as a subsidiary company asso- 
ciated with the American Metal Co.. the Metallurgical 
Co. of America (capital $2,000,000). 

As' the sphere of business interests of the Merton con- 
cern expanded into other countries outside of Germany, 
England, and the United States, the following addi- 
tional holding companies were organized : The Com- 
pagnie des Minerals, Liege (capital 2,500,000 francs) ; 
the Societe auxiliaire des Mines, Paris (capital 5,000,000 
francs) ; and the Compania de Minerales y Metales, 
Mexico. Together with the French banks, Cahen d'An- 
vers, the Societe generale pour favoriser le developpe- 
ment du Commerce et de l'industrie en France, and other 
capitalistic groups, the Societe des Cuivres et Pyrites, 
Paris (capital 30,000,000 francs), was organized in 1907 
for promoting the development of three Spanish copper 
companies, the San Platon, the San Miguel, and the Pena 
Copper Company. 

Two subsidiary companies of the Metallgesellschaft 
and of Henry R. Merton & Co. are the African Metal Co. 
and the Australian Metal Co. of London and Melbourne, 
respectively. They attend to the purchase and sale of 
metals in their respective parts of the world in behalf of 
the two parent concerns. 

In 1906 the Berg- und Metallbank A. G., located at 
Frankfurt, was organized with a capital of 40,000,000 
marks. This holding company was founded by the

Metallgesellschaft, together with the Metallurgische Ge- 
sellsehaft, the Deutsche Gold- und Silberscheideanstalt, 
the Damistadter Bank, the Berliner Handelsgesellschaft, 
the Diskontogesellsehaft, and several private bankers of 
Frankfurt. From one-quarter to one-third of the capital 
in the principal undertaking of the Merton concern was 
turned over to the Berg- und Metallbank. In 1910 the 
Berg- und Metallbank A. G. was consolidated with the 
Metallurgische Gesellschaft into the Metallbank und 
Metallurgische Gesellschaft A. G., Frankfurt a. M., with 
a capital of 40,000,000 marks. 

A chart showing the principal inter-relationships of 
the various companies in the group which centre in the 
Metallgesellschaft and the Metallbank und Metallurgische 
Gesellschaft has been prepared by the Commission, and 
is inserted in this volume. A preliminary chart was first 
prepared from information derived from a large number 
of published sources, chief among which were the article 
by Prof. Robert Liefmann in the 'Weltwirtschaftliches 
Archiv' for January 1913, various articles in the 'Na- 
tional Review' (London), the Mining and Engineering 
Review' (Melbourne), and other periodicals. The pre- 
liminary chart was then submitted for criticism to a 
number of Americans who are well informed in regard 
to the international metal situation and are acquainted 
with the organization, operation, and control of the com- 
panies shown on the chart. A final chart was then pre- 
pared, embodying the changes that were found to be de- 
sirable, in the light of the information gathered through 
such co-operation. The Commission believes that the 
chart herewith presented shows the principal companies 
and their inter-relationships, as they existed at the time 
of the outbreak of the present War. It is generally un- 
derstood that as a result of the War there have already 
been a number of changes in such relationships, and that 
more are likely to take place. 

It should be noted that the relationships shown on the 
chart indicate either stock control, stock inter-ownership, 
interlocking directorates, or syndicate connections. These 
relationships, the Commission is informed, are of such a 
nature that they lead to a centralized price control and to 
a harmony between the policies followed by the different 
companies in their purchases of metals. Connections 
also exist with other companies, but these have not been 
put on the chart because the Commission does not under- 
stand that they are effective in price control. 

In the group of companies which are largely the out- 
growth of the Merton concern, the dominating place has 
been held by the Metall Gesellschaft, the Metallbank und 
Metallurgische Gesellschaft, and the H. R. Merton & Co., 
Ltd. The affiliations of these companies through stock 
ownership and interlocking directorates is so close that 
it is difficult to determine which company is the domi- 
nating concern. The two largest subsidiary companies 
are the Merton Metallurgical Co. and the American 
Metal Co., Ltd. Apart from these two companies and 
their subsidiaries, the chart shows connections between 
the three controlling companies and 24 companies (ex- 
eluding the Deutsche Gold- und Silberscheide group). 



Most of the connections were through stock ownership, 
either alone or in connection with interlocking director- 
ates. In addition, mention is made of the fact that sim- 
ilar relations exist with 83 companies whose names are 
not separately* shown. 

While the chart shows 13 companies related to the cen- 
tral group through the American Metal Co., and a like 
number related through the Merton Metallurgical Co., 
attention should be called to the fact that many of these 
28 companies are, at the same time, connected with one 
or more of the central group and with other companies 
directly connected with it. In all, the chart shows the 
names of 54 companies of the 137 companies (excluding 
the Deutsche Gold- und Silberscheide group), of whose 
inter-relation to the Metallgesellschaft the Commission 
has information. Among the important companies not 
mentioned on the chart in which the Metallbank und 
Metallurgische Gesellschaft holds shares are the Societe 
des Anciens Btablissements 'Sop with' of Paris and 
Linares, the bank of Delbriick Schiekler & Co. of Berlin ; 
the Mittledeutsche Versicherungs, A. G., Diisseldorf ; the 
Allgemeine Revisions und Verwaltungs, A. G., Berlin; 
the Solotwina Naphta, G. m. b. II., Lemberg ; the Osterr. 
Petroleum-Industrie, A. G., Vienna. 

The Deutsche Gold- und Silberscheideanstalt. In 
1872 the Deutsche Gold- und Silberscheideanstalt was 
established by the firms of Fr. Roessler Sbhne and Hector 
Roessler, and in 1873 took over the precious metal busi- 
ness of Philipp Abraham Cohen. Close relations exist 
between the Merton interests and the Deutsche Gold- und 
Silberscheideanstalt, which is itself a widely ramified 
concern, is interested mainly in the chemical industry, 
and serves as the central agency for several cartels, 
among them the Convention of Manufacturers of Potas- 
sium Ferrocyanide, the Convention of Manufacturers of 
Potassium Cyanide, and the Convention for Quinine and 
Quinine Salts. 

On the chart the connections in the nature of either 
stock-ownership, interlocking directorates, or both are 
shown between the Deutsche Gold- und Silberscheidean- 
stalt and 20 minor companies. The dh-ect connections 
shown are principally through stock-ownership. In ad- 
dition to the connection shown on the chart with the 
Metallgesellschaft, the Commission has information con- 
cerning a number of inter-relations between companies 
of the Deutsche Gold- und Silberscheideanstalt group 
and those of the Metallgesellschaft, Metallbank und 
Metallurgische Gesellschaft, and H. R. Merton Co., Ltd., 
group, which it is not practicable to present diagram- 
matically. 

Abon Hirsch und Sohn. The firm of Aron Hirsch 
und Sohn, of Halberstadt, is an important unit in the 
international metal trade around which numerous sub- 
sidiary and otherwise related companies are grouped. 
It is also closely associated with a number of German 
and international cartels. It is one of the three selling 
agencies of the international zinc syndicate of Germany. 
It is a member of the German Copper Sheet Syndicate, 
Cassel, and of the Combine of German Copper Wire

Works, Cologne. It holds an interest in the Arm of Paul 
u. Siegberl Lachmann, the oopper mine Usenberg am 
Harz, and the brass works Eberswalde on the Pinow 
Canal, li controls the Eirsch, Kupfer- and Blessing 

. A. Q., in Balberstadt (capital 10.000.000 marks . 
which manufactures chiefly copper and zinc products for 
railways, shipbuilding, and military purposes. The Brm 
of Hirsch, Eupfer- und Messingwerke holds an interest 
in the Berlin Brass Works, Wilhelm Borchert, Jr., G. m. 
b. H. (capital 1,000,000 marks), and in the Rich. Herbig

Co., Ltd. 

In Australia Aron Hirsch und Sohn are interested in 
such important metal enterprises as the Electrolytic 
Smelting & Refining Co. and the Mount Morgan Gold 
Mining Co., Ltd., one of the largest Australian copper- 
producing companies. Through the latter company 
Aron Hirsch und Sohn are connected by common di- 
rectors with Goldsborough Mort & Co., bankers and 
brokers and with the Broken Hill Proprietary Block 10 
Co., Ltd. The international ramifications of the 
Hirsch interests also extend to numerous companies in 
the United States and Mexico. The firm of Ludwig 
Vogelstein & Co., New York, of which the firm of Aron 
Hirsch und Sohn is a special partner, serves as inter- 
mediary between the Hirsch interests and several of the 
American companies. The chart shows the names of 19 
companies which are connected directly or indirectly 
with the firm of Aron Hirsch through interlocking di- 
rectorates or stock-holdings. 

Beer, Sondheimer & Co. The firm of Beer, Sond- 
heimer & Co., Frankfurt a. M., is the centre of another 
large group of enterprises in the international metal 
trade, and ranks next in importance to the Merton con- 
cern, with which it has certain interests in common. In 
1906 Beer, Sondheimer & Co. founded the Tellus A. G. 
fur Bergbau und Hiittenindustrie. This company in 
turn controls, through stock-ownership, or interlocking 
directorates, 36 other companies, the names of 12 of these 
concerns being shown on the chart. Beer, Sondheimer 
& Co. also are connected with the National Zinc Co. (New 
York), and the Elder's Metal Co., of Australia. The in- 
ternational character of its business is seen from the fact 
that in the group are German, Austrian, Italian, Belgian, 
French, American, and Australian companies. 

The range of activities of the U. S. Bureau of Stand- 
ards is shown by the recent annual report of the di- 
rector, which states that 155,000 tests of weights, meas- 
ures, and instruments were made during this year, a 
new standard screen-scale and new gauge-standards for 
testing munitions gauges was prepared, together with 
investigations covering the accuracy of leather-measur- 
ing apparatus, standardization of blood-counting appa- 
ratus, standardization of master scales in 21 States and 
of those used by the American Railway Association, ex- 
tension of the work on altitude-measuring instruments 
including those used in aviation, and also special re- 
searches in the physics of materials.

Richards, the presence of manganese in the Boluti a 

nf advantage during electrolysis; in fact, at the electro 
lytic plant at Nelson, B. < '., a manganese salt is said to be 
added to the solution I ause of its beneficial action dur- 
ing tin' electrolysis. Tin- manganese separates out on the 
anodes as manganese di-oxide, helping to prolong their 
life and also furnishing indirectly a method of extract- 
ing the manganese from the raw materials used in the 
manufacture of the soluble manganese salt. It is quite 
true, however, that small amounts of certain impurities 
render difficult the deposition of the zinc in coherent 
form, and great care must be taken to maintain the 
purity of the electrolyte. He takes exception to the state- 
ment that all the factors necessary to the production of 
electrolytic zinc were known long ago. One of the most 
important factors recently determined is the extent to 
which the zinc can be extracted from the solution, leav- 
ing the solution acid. Many thousands of dollars have 
been spent in experiments during the last few years to 
determine just how far the electrolysis can proceed and 
the acidity of the solution be increased without decreas- 
ing too much the deposition of the zinc. He thinks that 
not enough emphasis has been placed on the possibility of 
the electrolytic methods replacing the retort methods for 
zinc. He bases his prediction on the fact that the retort 
methods have been used for over a hundred years and at 
the present time are being only very slowly improved, 
whereas the electrolytic methods have been in use not 
more than five years and are susceptible of very much 
greater improvement. He thinks that where one may ex- 
pect a possible improvement of 10% in the retort proc- 
esses in, let us say, the next five years, there is a possi- 
bility of an improvement of perhaps 50% in the electro- 
lytic processes. One must not overlook the possibility 
of a relatively much greater improvement in the new 
electrolytic methods, and he affirms that the Joplin 
territory will very soon see an invasion of electrolytic 
zinc, as has been pointed out, for their special concen- 
trates or special kinds of ore. — Amer. Inst. Min. Eng. 

Alaskan mines are believed to have produced gold to 
the value of about $15,450,000 in 1917, compared with 
$17,240,000 in 1916. The total value of the gold mined 
in the Territory is now about $293,500,000, of which 
$207,000,000 has been won from placers. In 1917 about 
88,200,000 lb. of copper was produced in Alaska, valued 
at about $24,000,000. The production in 1916 was 119,- 
600,000 lb., valued at $29,480,000. The total copper 
produced to date is 427,700,000 lb., valued at $88,400,000. 

Pyrites from domestic sources is now quoted at 25 
to 30c. per unit of contained sulphur. Spanish pyrites 
is still quoted at 16c. per unit, but foreign prices are 
based on the freight rates. The seller pays up to 13 
shillings and the buyer the difference. Freights today 
are from 30 to 35 shillings per ton.

California Metal Production in 1917 



January 19, 1918 



The mines of California made an output in gold, silver, 
copper, lead, and zine, valued in all at $41,457,692 in 
1917, compared with $39,749,263 in 1916, according to 
preliminary figures compiled by Charles G. Yale of the 
San Francisco office of the U. S. Geological Survey. 
This is an increase of $1,708,429. 

The mine output of gold in 1916 was $21,410,741. The 
estimated output of gold in 1917 is $21,098,915, a de- 
crease of $311,826. If this estimate is correct, the slight 
decline in the gold output of the State in 1917 as com- 
pared with 1916 is much less than has been expected in 
view of conditions that have existed since the United 
States entered the War. These conditions have affected 
the deep mines more unfavorably than the placer mines. 
There has been, and still is, a scarcity of skilled labor, 
as machine-men, timber-men, and skilled miners have 
been attracted elsewhere by the higher wages paid in 
munition factories, copper and coal mines, and other in- 
dustries that supply demands made urgent by the War. 

The higher cost of nearly all mining supplies, and the 
increased taxation have made it impossible to operate at 
a profit some of the large mines that have been working 
low-grade ore. A number of the smaller mines have 
therefore already been closed, and some of the larger 
ones will stop ore-producing and milling ore this winter, 
and will do development work only and keep down the 
water. Some operators say that the purchasing power 
of gold has so greatly declined that they are virtually 
getting only about $10 an ounce for their gold. Meetings 
were held in San Francisco in December by the promi- 
nent gold operators to protest against any discrimination 
through freight priorities aimed at the mining of gold as 
non-essential to the conduct of the War. It was feared 
also that the supply of explosives for use in mining 
might be cut off on the same ground. These apprehen- 
sions and the existing conditions have caused great un- 
rest among gold miners, and as a result prospecting and 
development have almost stopped. 

The deep mines of California are now producing about 
60% of the gold output of the State, the other 40% 
coming from the various placer mines, principally 
through dredging. The proportion of the gold output of 
the State derived from placers is thus increasing. The 
gold-dredging industry continues prosperous, and few 
changes have occurred in the general conditions. In all 
the larger enterprises a greater effort is being made to 
save more gold. A few dredges are re-working old tail- 
ings with profit. Some of the largest and most expensive 
dredges ever built have been put to work in 1917. A 
number of old dredges have been dismantled and their 
machinery has been put into boats for use at new places. 
A few have gone out of commission altogether, their 
available ground having been worked out. Some new 
machines have been installed on new ground in the 'out- 
side' districts of the State. Neither hydraulic nor drift 
mining shows any marked revival, though several old 



hydraulic mines that have been idle for more than a 
quarter of a century have been re-opened, and search is 
being made for available ground where conditions are 
favorable for constructing the dams and basins required 
for impounding the debris. 

The output of silver is estimated at 2,144,196 oz., 
valued at $1,745,375, as compared with 2,564,354 oz., 
valued at $1,687,345 in 1916. This silver was derived 
mainly from copper and lead ores, although some is 
mined with the gold. Owing to the rise in value of 
silver, a number of old mines in San Bernardino and 
Inyo counties that were once worked profitably, but that 
for years have been idle, are now being re-opened. 
Notable among these are the mines at Calico, which were 
at one time large producers. None of these properties, 
however, yielded much silver in 1917. 

The estimated mine output of copper is 57,591,195 lb., 
valued at $15,664,805, as compared with 55,897,118 lb., 
valued at $13,750,691 in 1916. Labor troubles during 
the year restricted somewhat the output of the most pro- 
ductive copper mines in the State, and thus affected the 
total. Shasta county was by far the largest producer in 
1917, but Calaveras, Placer, and Plumas counties now 
have very productive mines, with their own reduction 
plants, and there are many smaller productive copper 
mines in other counties. 

The output of lead in 1916 was 12,407,493 lb., valued 
at $856,117 ; the estimated output in 1917 is 23,189,974 
lb., valued at $2,133,460. Nearly all the lead comes 
from Inyo, San Bernardino, and other counties in the 
southern part of the State. 

The estimated output of zinc in 1917 is 9,158,851 lb., 
valued at $815,137. as compared with 15,256,485 lb., 
valued at $2,044,369 in 1916. The zinc comes entirely 
from Shasta and Inyo counties. Every one of the larger 
companies made a reduced output in 1917. 

Alaskan Mineral Output in 1917 

In 1917 Alaska produced minerals valued at $41,760,- 
000, as determined by an advance estimate by G. C. 
Martin of the U. S. Geological Survey. This is about 
$6,870,000 less than that in 1916. The leading product 
was copper, being 88,200,000 lb., valued at $24,000,000. 
This is less than the output of 1916, which was 119,600,- 
000 lb., valued at $29,480,000, but is greater than that of 
any other year. The reduction is due largely to labor 
troubles, and is not necessarily permanent. The gold 
production was $15,450,000, of which $9,850,000 was 
derived from placer mines. The reduction from $17,240,- 
000 in 1916 was due chiefly to curtailment due to the 
scarcity of labor and the high cost of materials, but, in 
part, to the disaster at the Treadwell mine and the de- 
pletion of some of the richer placers. Alaska also pro- 
duced silver, valued at $1,050,000, coal worth $300,000, 
lead $160,000. tin $160,000, antimony $40,000, and tung- 
sten, chromium, petroleum, marble, gypsum, graphite, 
and platinum, valued at $600,000.

Mining in the Norths West 



By FRANCIS A. THOMSON 



While there may have been slightly less activity dur- 
ing 1917 than in 1916, the year as a whole has been a 
prosperous one in the North-West. Changes in market 
conditions and in the lahor situation brought about by 
our entry into the War have disturbed operations, but 
the situation as a whole, provided relief from the war- 
tax is secured, is fairly promising. • 

The supply of labor has been reasonably adequate. 
The lead-gold-silver mines are having to pay a price 
dictated largely by conditions in the copper districts, 
without the compensation of a fixed price at a fairly 
high level. The miners, however, have shown less dis- 
position to listen to anarchism and the I, W. W. than 
the workmen in other industries. 

The extension of smelting facilities at Northport and 
the entrance of the Bunker Hill & Sullivan company 
into the ore-market have been favorable features for the 
lead-gold-silver mines. The closing of the Trail smelter 
across the line and the reduced scale of operations at 
the B. C. smelter at Greenwood and at the Granby plant 
at Grand Forks due to coke shortage have hurt the 
small copper producers. 

No material change in transportation facilities has 
taken place, if we except the Pine Creek branch of the 
0. W. R. & N, which will afford an outlet for the prom- 
ising zinc-lead producers of this comparatively new dis- 
trict of the Coeur d'Alene region. 

In the line of legislation the outstanding feature of 
the year is, of course, the War Tax law, which, because 
of its inequities and "inartifieialities, " as Judge 
Turner's pleasant euphemism has it, promises to bear 
with great harshness on those concerns which have been 
commendably conservative in the matter of capitaliza- 
tion. Doubtless relief will come in time, but meanwhile 
some of the mining companies are having to cancel divi- 
dends to stockholders in order to declare them in favor 
of the tax-gatherer. Against this the mine-owners would 
not protest if they felt that all other concerns were car- 
rying an equal load. A second line of Federal legisla- 
tion that directly affects the mining industry is the 
Explosives Act. This is designed to prevent explosives 
falling into the hands of alien enemies and is a highly 
commendable piece of legislation. The administration 
of the law is placed in the hands of the Director of the 
Bureau of Mines, who is given full authority for carry- 
ing out its provisions. The fear that the administration 
of the act might result in restriction of mining opera- 
tions does not seem justified. 

The year has been singularly devoid of new discoveries. 
Several of the larger properties in the Coeur d'Alene 
have responded favorably to new development, and the 



Pine Creek district should soon begin to make a place 

for itself in the zinc and lead statistics. 

An interesting innovation is the dredging operation 
that the Yukon Gold company is beginning near Murray 
on the north fork of the Coeur d'Alene river, one of the 
Yukon boats having been 'transplanted' for the purpose. 

In Stevens county the continued development of the 
great magnesite deposits and the erection of kilns, with 
the steady shipment of both calcined and raw products, 
continues to he a gratifying feature of the contribution 
that our mineral deposits are making to the War. At 
Loon Lake, also in Stevens county, development of cop- 
per prospects long known but little valued is proceeding 
with encouraging results. In a small way the same thing 
is true of the copper prospects in the Hoodoo district 
of Latah county. Good reports continue to come in from 
the Marshall Lake district in central Idaho, and several 
other quartz properties in this once famous placer 
locality are giving evidence of new life. 

The outstanding feature in metallurgical construction 
is the Bunker Hill & Sullivan smelter. Designed by the 
most experienced firm of smelter engineers in the West, 
and with the greatest silver-lead mine in the world to 
supply the wherewithal, it stands as the last word in 
this type of construction. Of steel and concrete through- 
out, it affords a startling contrast to the older plants, 
which, like Topsy, have "just growed" in response to 
an ever-varying ore-supply. From automatic charge- 
weighing hoppers to refinery, and from Dwight-Lloyd 
roasters to bag-house and Cottrell plant, everything is 
as complete as money and brains can make it. 

Flotation continues to find wider application, the ten- 
dency being about equally divided between pneumatic 
and agitation machines of various types; and so far the 
Minerals Separation company seems disposed to content 
itself with an occasional circular letter to the operators. 

To the student of mining litigation the year has been 
unusually interesting, there having been three major 
cases, each of a different character, involving in turn the 
three greatest properties of the Coeur d'Alene. First is 
the suit of the American Smelting & Refining Co. against 
the Bunker Hill & Sullivan company, by which the former 
claims breach of contract and seeks to prevent the latter 
from treating its own ore in its own smelter. From the 
appearance of things at the new smelter it is evident 
that the owners of the Kellogg plant have no expectation 
of being put out of business. The next suit in point of 
interest is the apex litigation of Star v. Federal, involv- 
ing ownership of orebodies adjacent to the Morning 
mine at Mullan. As in most cases of the kind, the public 
has been highly edified by the startling differences of 



94 



MINING and Scientific PRESS 



January 19, 1918 



opinion among eminent members of the mining profes- 
sion upon matters where substantial unanimity would 
be expected. The man in the street begins to wonder 
whether economic determinism has not become a con- 
trolling factor among the adherents of a certain school 
of geological opinion. Like other defects in our system 
of litigation, the matter of ex parte expert testimony has 
waited long for remedy. Decision on this case has not 
yet been rendered; the orebodies in question are exten- 
sive and valuable and the future of each of the parties 
to the suit depends to a considerable extent on the out- 
come. Either a comparatively unknown prospect will 
at once become a big mine or the Star company will lapse 
back into obscurity and the great Morning mine will 
pursue the even tenor of its way. The last great suit of 
the year is that of Cardoner v. Day for annulment of 
sale on grounds of alleged fiduciary relationship between 
buyer and seller, and of inadequacy of consideration. 
Late in 1916 Mrs. Cardoner received $375,000 for her 
one-sixteenth interest in the Hercules mine. Testimony 
concerning the value of the property involving princi- 
ples of mine-valuation was offered by defendants them- 
selves and by their engineer to the effect that the present 
value of the property was approximately $5,000,000, on 
which basis Mrs. Cardoner received a fair consideration 
for her interest. Mrs. Cardoner 's engineer places the 
value of the total ore in the mine at $10,750,000 and 
assigned a life of 13f years to this amount of ore at 
present production. The present value of this amount 
of ore distributed over 13f years at any rate of interest 
between 7 and 10% is from $4,500,000 to $5,000,000. 
This corroborates the testimony of the defense. Decision 
is expected any day. 

The effect of the War on mining is disquieting. The 
demand for lead is sluggish, due doubtless to a cessation 
of normal construction and painting demands, to the 
fact that ammunition is being made largely in England, 
and that lead supplies for this are presumably coming 
from Spain and Australia. In zinc the situation is dis- 
quieting, partly because England is becoming a large 
producer from Australian ores, and at the Government 
price for copper many of the smaller producers are not 
making much money. We are getting subnormal prices 
for the metal and paying abnormal prices for labor and 
supplies. Having been smitten on this cheek, Uncle 
Samuel asks us to turn the other one and let him swat 
us with an ill-considered war-tax. The possibility of 
dollar silver is the one ray of hope on the horizon of the 
coming year. 

In conclusion, lest this be considered a tale of woe, let 
me say from an intimate contact with the mining indus- 
try of this part of the North-West, that those respon- 
ible for the productive operations are not only able and 
willing, but even anxious, to carry their share of the war 
load. They are giving their valued technical men to the 
Army, they are subscribing and over-subscribing to 
Liberty loans, and they are donating to 'drives' without 
stint. As one operator put it a few weeks ago, "Uncle 
Sam can have all we've got if it's necessary in order to 



lick the Kaiser, he can take our mines and our mills if 
need be, and we '11 live on turnips and carrots if Hoover 
says so, but at the same time we expect the other in- 
dustries to tote their fair share of the load." 

Mineral Production in South Africa 



The value of all the minerals produced in the Union 
of South Africa for the month of August amounted to 
$17,569,277. The gold production was 757,202 fine 
ounces, valued at $15,652,557, of which the Transvaal 
alone yielded 757,146 fine ounces, worth $15,651,404. 
The Union also produced 944,757 tons of eoal, worth 
at the pit's mouth $1,435,019, of which the Transvaal 
contributed 618,314 tons, worth $717,342, and the Or- 
ange Free State 76,833 tons, valued at $96,259. The 
copper production of the Union amounted to 593 tons, 
valued at $142,720. Out of 225 tons of tin produced, the 
Transvaal supplied 223 tons, worth $167,904. The profit 
earned by the Transvaal gold mines in August fell to 
$4,287,387. With the exception of that for February, the 
return is the lowest for this year, and compared with 
August 1916 it is a reduction in profits amounting to 
$574,247. However, the Rand companies show a profit of 
$34,084,966 for the eight months of the present year. 
During the past year working-costs have advanced on the 
Transvaal gold mines from $4.38 to $4.66, of which 12c. 
per ton has been neutralized by higher recovery. It is 
noticeable, however, that the tonnage handled is 126,000 
lower than a year ago. In August the Rand output 
amounted to $15,111,930, equal to $6.51 per ton; work- 
ing-profits were $4,182,839, representing $1.82 per ton. 
The general aggregate was severely affected by the poor 
profits of certain mines in the Germiston district, but 
fortunately the splendid progress of the Far Eastern 
Rand was more than maintained. The 10 mines of that 
district show profits totaling $2,034,197, or nearly half 
the profits of the whole Rand. Eight of these mines 
made a profit of over $2.43 per ton, while four returned 
over $486,500 worth of gold. The total mineral pro- 
duction of Southern Rhodesia for August amounted to 
$1,789,076. Of this, the output of gold reached 70,259 
fine ounces, worth $1,432,499, and the yield of silver was 
17,768 oz., worth $10,886. 

The Federal Aid Road Act is benefiting all the States 
of the Union. The appropriation was 75 million dol- 
lars for the construction of post-roads and 10 million 
for forest-roads. In 1916 there were approximately 41 
million dollars of State funds expended for all highway 
purposes, and it is estimated that in the calendar year 
1917, the aggregate expenditures of State funds for 
this purpose will be at least 60 millions. A number of 
the States have made appropriations to meet the Fed- 
eral aid dollar for dollar. Further information re- 
garding this work may be obtained from the Director 
of the Office of Public Roads of the Department of 
Agriculture.

Nevada Mine Output in 1917 

The value of the gold, silver, copper, lead, and zinc 
mined in Nevada in 1917 was over $53,000,000, according 
to preliminary figures compiled by Victor C. Heikes of 
the U. S. Geological Survey. This total represents an 
increase of over $3,000,000 in spite of the fact that there 
was a slight decrease in recoverable zinc and a marked 
decrease in both gold and silver. There was a fair in- 
crease in the output of both copper and lead. The aver- 
age prices of silver, copper, and lead were unusually 
high in 1917, aud this fact had much to do with making 
the total value greater than that of the previous year. 

The gold output of Nevada was valued at about $6,- 
852,000, a decrease of about $2,000,000. This decrease 
was due in great part to the reduced output of the Gold- 
field Consolidated Mining Co., which has for years been 
the main gold-producer of the State. The production of 
the Tonopah district, the ores of which contain consider- 
able gold, was also less. The gold output was valued at 
about $1,612,000, against $1,941,441 in 1916. The main 
producers were the Tonopah Belmont, Tonopah Mining 
Co., Jim Butler, Tonopah Extension, and West End. 
Much gold came from the Elko Prince, the Aurora Con- 
solidated at Aurora, the Bound Mountain placer and 
quartz properties, the Bochester district, and the mines 
at Manhattan, where there was renewed activity. At the 
White Caps mine a large orebody is developed from five 
levels. The new mill, with roaster, was active during the 
last, part of the year, making a considerable output. The 
War Eagle, Big Pine, and Union Amalgamated mills 
were also operated, and a large amount of placer gravel 
was treated by 12 operators. Bullion production from 
Seven Troughs district decreased, as did the placer out- 
put from the Battle Mountain district of Lander county, 
but the mills in Eldorado canyon, in Clark county, were 
unusually active. The National mine, a large producer 
in the past, was unproductive in 1917. About one-sixth 
of the gold came from copper ore and lead ore, mainly 
from copper ore. 

The production of silver decreased from 13,837,525 oz. 
in 1916 to about 11,394,000 oz. in 1917. The price of 
silver, which averaged about 81 cents per ounce, gave this 
output a value of $9,229,000, which is slightly more than 
in 1916. The principal silver-producers were the mines 
at Tonopah, the Nevada Wonder, the Rochester Mines 
Co., Nevada Packard, Elko Prince, Comstock properties, 
Yellow Pine, and Nevada Hills. With the improved 
price it was possible to treat low-grade ore, especially at 
Tonopah, where the silver output decreased to about 
7,500,000 oz. from 8,734,726 oz. in 1916. The Tonopah 
Belmont, Tonopah Mining, and Tonopah Extension each 
produced more than 1,000,000 oz. of silver as well as con- 
siderable gold. The Mexican mill at Virginia City 
treated custom ore, largely from the Union Consolidated 
mine, but the bullion output of the district was much less. 

The copper production of Nevada increased to nearly 
110,000,000 lb., an increase of nearly 5,000,000 lb. over 



that of the previous yeaa The vain.- of the outpul in- 
creased from $25,S;->S,7:!6 to about $32,1)1)0.000. The main 
copper-producer, as formerly, was the Nevada Consoli- 
date! ;il McGill. This company was milling over 300.- 
Ot it I Ions of ore per month and shipped a lirsl class prod- 
uct. The production from the smeller was somewhat less 
than in 1916, but the loss was more than compensated by 
the operation of the Mason Valley plant, in Lyon county. 
A large part of the ore treated came from the Bluestone 
mine, considerable quantities of copper ore were shipped 
to other copper plants, especially from the Yerington dis- 
trict in Lyon county, the Santa Fe and Silver Star dis- 
tricts of Mineral county, and from the Robinson district 
in the vicinity of Ely. The Copper Canyon Mining Co., 
in the Battle Mountain district, made a large output. 
The Consolidated Copper Mines Co., at Ely, contributed 
a noteworthy quantity of both crude ore and concen- 
trates. The mill was remodeled and improved, and 
toward the close of the year treated more than 600 tons 
per day. 

The production of lead increased from 25,637,278 lb. 
in 1916 to over 28,000,000 lb. in 1917. The value of the 
output increased from $1,768,972 to about $2,537,000. 
The principal lead-producing districts are the Pioche of 
Lincoln county, particularly the Prince Consolidated 
mine, and the Yellow Pine district of Clark county. The 
Bullion and Goodsprings Anchor properties, in the Yel- 
low Pine district increased their output of lead. Con- 
siderable ore was mined at the Groom property, in south- 
western Lincoln county, at the Hamburg property near 
Pioche, at the Union Mines Co., and at properties in the 
Eureka district of Eureka county. 

There was a decrease in the production of recoverable 
zinc from 32,443,189 lb. in 1916 to about 28,500,000 lb. in 
1917. The value of this output decreased considerably 
from over $4,000,000 to about $2,613,000. The Yellow 
Pine property, in Clark county, continued to supply the 
largest quantity of zinc produced by any mine in the 
State. The Potosi mine of the Empire Zinc Co. was also 
a large producer. Zinc was also produced by the Nevada 
Zinc Mining Co. in Elko county, the Lone Mountain dis- 
trict in Esmeralda county, and Ely in White Pine county. 

The dividends declared by Nevada mining companies 
in 1917 amounted to over $11,000,000. The largest was 
that of the Nevada Consolidated, which paid over $8,- 
000,000. Others were the Tonopah Belmont, Tonopah 
Mining Company, Jim Butler, Yellow Pine, Nevada 
Hills, Tonopah Extension, Boss, West End, Hamburg, 
Nevada Wonder, Uvada, Rescue Eula, and Prince Con- 
solidated. 

Lithophone manufacturers are so far sold out that 
they are reported to be withdrawing from the market. 
The market is strong, with prices advanced as high as 
7c. per pound, and predictions are for still higher figures. 
Prices of zinc oxide are also good, spot commanding 12^ 
to 14c. Producers are sold out three months ahead, with 
contract prices at 14c. for white seal, and '13c. for red 
seal.

Metal Mining in Montana in 1917 

The value of the gold, silver, copper, lead, and zinc 
mined in Montana in 1917, according to the estimate of 
Victor C. Heikes of the U. S. Geological Survey, was 
nearly $113,000,000, a decrease of more than $20,000,000 
from the value in 1916. There was an increase in the 
production of lead in the State, hut a marked decrease in 
that of gold, silver, copper, and zinc. The mines at Butte 
and the smelters at Anaconda and Great Falls were idle 
two months on account of labor strikes. The prices of 
metals, except zinc, were unusually high. The cost of 
labor and material was also high. 

The gold mined was valued at $3,371,000, as compared 
with $4,550,494 in 1916. The decrease in the output of 
copper ore reduced the output of both gold and silver. 
A marked decrease was also recorded in the gold won by 
dredges at Alder Gulch. There was an increase in gold 
bullion from the Barnes King properties, especially the 
Shannon mine at Marysville. Some bullion came from 
the new mill of the Bannaek Gold Mining Co., at Ban- 
nack, in Beaverhead county. There was considerable 
activity in the Warm Springs district of Fergus county. 

The output of silver decreased from 16,494,366 oz. in 
1916 to about 12,788,000 oz. in 1917. In spite of the in- 
creased price, the value ($10,358,000) was nearly $500,- 
000 less than in 1916. Nearly all the silver is derived 
from copper ore, the production of which decreased for 
the year. 

The output of copper in 1917 was about 278,000,000 lb., 
a decrease of nearly 75,000,000 lb. The value of the out- 
put was about $81,000,000, against nearly $87,000,000 in 
1916. Practically all the larger copper producers made a 
smaller output than during former years, especially the 
Anaconda and North Butte. On the other hand, there 
was a slight increase from East Butte. In March the 
Anaconda plants produced over 31,000,000 lb. of copper. 
Had this rate continued for the year, Montana- would 
have had a largely increased copper output, but the in- 
dustry was seriously affected by the closing of the mines 
and plants in July, August, and part of September. 
Shipments were made from the Tuolumne, Davis Daly, 
and Bullwhacker mines, and a good output came from the 
Butte & Duluth leaching plant. 

The mine output of lead increased from 13,595,136 lb. 
in 1916 to about 17,000,000 lb. in 1917. The price of 
lead evidently stimulated work on many of the lower- 
grade lead mines. The lead concentrate from lead-zinc 
ore was less, however, on account of the decrease at the 
large zinc mines. At Troy, in Lincoln county, the new 
mill of the Snowstorm Mines Co. was producing both 
lead and zinc concentrate in July, and marketed consid- 
erable quantities of both products* The Valley Forge 
mine, in Lewis and Clark county, shipped much lead ore 
to Helena for concentration. 

The output of recoverable zinc from Montana amount- 
ed to about. 180,000,000 lb., against 229,259,075 lb. in 
1916. Prices were lower in 1917, but the decrease was 



also due in part to labor troubles and to a lawsuit be- 
tween the two chief zinc-producers of the Butte region. 
During the first quarter of 1917 the Butte & Superior 
Mining Co. produced over 40,000,000 lb. of gross zinc, 
but it did not maintain this rate of production throughout 
the year. The Elm Orlu produced some ore but con- 
siderably less than in 1916. The rest of the output of the 
State came from the mines of the Anaconda company, 
the product of which is leached at Great Falls after 
being concentrated. Other shipments of zinc were made 
from the Snowstorm at Troy and the North Butte at 
Butte. 

The dividends for 11 months amounted to over $23,- 
000,000. The principal dividend-payers were the Ana- 
conda, Butte & Superior, North Butte, East Butte, 
Barnes King, and Butte-Bullwhacker. 

Oregon Metal Production in 1917 

A preliminary estimate of the production of metals 
from Oregon mines in 1917, compiled by Charles G. Yale, 
of the San Francisco office of the U. S. Geological Sur- 
vey, shows a material decrease from that of 1916. The 
output of gold in 1916 was $1,902,149, and the estimated 
output in 1917 is $1,466,419, a decrease of $435,760. The 
output of silver in 1916 was 231,342 oz., valued at $152,- 
223, and the estimated output in 1917 is 115,697 oz., a 
decrease of 115,645 oz. in quantity and $58,046 in value. 
The output of copper in 1916 was 3,501,886 lb., valued at 
$881,144, and the estimated output in 1917 is 1,508,639 
lb., valued at $410,349. A small quantity of lead was 
produced in 1916, but no production of this metal has 
been reported for 1917. 

There are about a hundred productive mines in Ore- 
gon, and although two-thirds of them are placer mines, 
the larger part of the output of gold comes from the 
deep mines, and, of course, virtually all the output of 
the other metals. There were no important discoveries 
in any of the mining districts of Oregon in 1917, and no 
great increase in the output of any of the more produc- 
tive properties. The entire output of ore from all the 
deep mines combined does not exceed 160,000 tons. Most 
of the placer mines are worked by the hydraulic system, 
but the three dredges now in use produce far more gold 
than all the other placer operations combined. The 
largest output of gold and other metals in 1917 came, as 
usual, from Baker county, which produces annually 
about 90% of all the gold mined in the State, Josephine 
county is next in production. 



Zirconium minerals are chiefly used as a refractory 
material. The linear co-efficient of expansion of pure 
fused zireonia is 0.00000084. It is not only heat-resist- 
ing, but does not react as a flux to form slag. It is par- 
ticularly desirable for laboratory refractory ware, such 
as crucibles, muffles, combustion tubes, resistance cores, 
and the like. Zireonia has a low conductivity, and re- 
fractory ware made of it must be thin-walled.

TONOPAH, NEVADA 

Tonopaii .Mining. — Tonopah Extension. — Tonopaii Belmont. 
— West End Con. — Jim Butler. 

The Tonopah Mining Co. continues to ship ore from the old 
dumps at the rate of 2500 tons per week to the plant at Millers. 
Commencing the first of the year about 150 tons of mine ore is 
being shipped to the Belmont mill daily. Arrangements have 
been made whereby the production of the Tonopah Mining Co. 
will be treated at the Belmont mill when the production does 
not justify the operation of the 100-stamp mill at Millers. Dur- 
ing the past week 2400 tons of ore was milled, averaging $10 
per ton. At the Silver Top 32 ft. of development has been done 
and 42 ft. at the Sandgrass. At the Silver Top on the 340-ft. 
level the raise on the Burro No. 2 vein shows an increase in 
width and value. A raise has been started on the Upper Sand- 
grass vein from the 1140-ft. level of the Sandgrass. Last 

week's production was 2900 tons. The Tonopah Extension 

Mining Co. shipped 24 bars of bullion valued at $55,264. At 
the No. 2 shaft 90 it. of development has been done and 169 ft. 
at the Victor. At the No. 2 shaft on the 1260-ft. level raise No. 
450 was advanced 35 ft. on a 3-ft. face of ore. On the 1350-ft. 
level raise No. 567 continued in good ore and holed through 
into the level above. On the 1680-ft. level of the Victor the 
1600 east drift advanced on a 4-ft. face of ore, while the 1600 
west drift continues on a 6-ft. face of ore. The 1600 south 
cross-cut made 5S ft. of progress. The production the past 

week was 2380 tons. The Tonopah Belmont Development Co. 

will operate its mill at capacity, as arrangements have been 
made to handle all the ore from the Jim Butler Tonopah Min- 
ing Co. and part of the Tonopah Mining Co. output. On the 
700-ft. level east drift No. 721 on the Shoestring vein shows 
li ft. of ore. Raise No. 8 from drift No. 721 is making good 
progress on the Shoestring vein. On the SOO-ft. level east 
drift No. 8017 on the South vein struck a fault; but the vein 
was recovered. The west drift No. S01S also struck a fault. 
On the 1100-ft. level raise No. 94 on the Western vein continues 
on a lJ-ft. face of medium-grade ore. Last week's production 

was 2285 tons. The West End Consolidated Mining Co. 

shipped 40 bars of bullion valued at $74,061. Driving to the 
west in drift No. 535 continues in a full face of excellent ore. 
Winze No. 534 is progressing in ore. Raise No. 814 has 
reached the foot-wall of the vein. The output the past week 
was 1247 tons. At the Halifax Tonopah Mining Co. the 1018 
cross-cut struck a small vein. Work has been suspended in the 

1708 cross-cut awaiting the erection of a larger fan. The 

Jim Butler Tonopah Mining Co. produced 746 tons of ore. 
On the 200-ft. level of the Wandering Boy raise No. 373 con- 
tinues on a 3-ft. face of medium-grade ore. On the inter- 
mediate at the Desert Queen raise No. 654 uncovered ore. 

The MacNamara Mining Co. shipped seven bars of bullion 
valued at $11,700. Work in the raise on the. 700-ft. level has 
been suspended for the present, and work in the west cross- 
cut has been resumed to allow for the exploration of the vein 

by raises. The production the past week was 517 tons. 

With the completon of shaft repairs, work has been resumed 
in the raise from the SOO-ft. level of the Monarch Pittsburg 
Mining Co. The Montana produced 42 tons, and miscellan- 



a 6] Ions, making the week's production at Tonopah hi. 17s 

Ions with a gross value of $1S7,115. During the past year 

the mines al Tonopah produced 485,000 tons of ore, having an 
approximate value of $S,640,000. During the period $1,S70,30» 
was paid in dividends making the total dividends to date 
(30,669,548. 

MAMMOTH, UTAH 

Ti.ntic Standard. — Eureka Lily. — Ti.vnc Delawabe. — Ore 
Shipments. — Iron Kino. 

At the Colorado Consolidated, which is a consolidation of the 
Colorado and Beck Tunnel mines, prospecting is being done on 
the 1100-ft. level, where a drift is being driven toward the 

south-east. At the Zuma work is being carried on in the 

win?e as well as in the cross-cut on the 500-ft. level. In both 

places the showing is satisfactory. The shaft at the Copper 

Leaf Mining Co., which has been cutting through an exceed- 
ingly hard formation, is now in softer rock and much better 

progress is being made. The shaft is down 430 ft. J. H. 

McNellis of Silver City, who is superintendent for the new 
owners of the Scotia property of West Tintic, states that the 
new machinery is now in place and that the development of 
the mine will be under way within the next week. It is the 
intention of the owners to thoroughly prospect the upper 
workings of the mine and if necessary go deeper with the 
main working shaft. The new equipment consists of a 12 by 
12 compressor, a 30-hp. gasoline hoist, and a new cage. The 
shaft has been re-timbered. The Tintic Standard is ship- 
ping two carloads of first-class ore daily. If cars can be secured 
the Standard will be able to ship at the rate of 100 tons of ore 
daily. In the newer workings north-east of the shaft, and also 
in the older part of the mine an immense tonnage of ore is 
exposed and the property promises to be one of the big pro- 
ducers of the district during 1918. At the Eureka Lily 

mine, where the gas has been interfering with the work, a 
connection has been made which has relieved the situation. 
On the 1400-ft. level of the Eureka Lily drifts are now follow- 
ing two important veins and later raising will be started for 
the purpose of following a bunch of ore above the 1400-ft. 
The work is being carried on in a big mineralized area similar 
to that existing in the neighboring mine and it is hoped that 
only a little work will be needed to bring the mine into the 
productive stage. The orebody of the Tintic Delaware is in- 
creasing with depth. This is being demonstrated by develop- 
ments in the new workings, where carbonates are being re- 
placed by sulphides in the bottom of the winze, which is now 
down 15 ft. For some time past the company has been de- 
veloping a big body of high-grade lead-silver ore in the face 
of the adit and the work has demonstrated the deposit to be 
at least 30 ft. wide. Assays from the face ran up to 82% lead 
and 8 to 10 oz. silver. It is planned to sink the winze to a 

depth of 50 ft. to prove the permanency of the orebody. The 

total shipments of first-class ore from this district amounts to 
169 carloads as compared with 118 for the previous week. 
The principal shippers were Dragon Consolidated 43 cars, 
Chief Consolidated 18, Eagle & Blue Bell 17, Iron Blossom 16, 
Grand Central 15, Centennial Eureka 13, Mammoth 11, Tintic 
Standard 10. Gold Chain 5, Empire Mines 5, Victor 4, Colorado

2, Scranton 2, other mines 8 cars, making the total 169. A 

short time ago a trial shipment of iron ore was sent out from 
the Iron King property in the eastern end of the Tintic dis- 
trict and following the arrival of this ore at the smelter a 
satisfactory contract has been signed permitting the shipment 
of several hundred tons of the same character of ore which is 
now on the dump at the mine. The contract for the hauling 
of this ore between the mine and the railroad has been 
r warded to the Robertson Brothers of Eureka. There is an 
extensive supply of iron ore at the property and in the event 
of a railroad being built into that section the ore would be 
valuable to the company. 



PLATTEVILLE, WISCONSIN 

Blenhe. Galena, and Pyeite Prices. — Ore and Concentrate 
Shipments. 

The month of December compares favorably with the records 
shown for other months of the year when operating conditions 
were far more favorable to the miner. Severe cold and heavy 
snow falls followed by windy spells obliterated roads and com- 
pletely isolated many strong producers, making deliveries of 
zinc ore at times out of the question. To further cripple 
transportation facilities, at best none too good, for several 
months 20 engines were removed from the Galena division of 
the Northwestern Railway under orders of the War Depart- 
ment. This line gives immediate service to every mining 
district in the field and the carrying out of the order impaired 
the railway service so seriously that many small operating 
companies were compelled to suspend operations for the re- 
mainder of the winter. Price offerings while more nearly in 
adjustment with the price of spelter were regarded as unsatis- 
factory by miners because of the excessive cost of operating. 
Powder is now being sold at $500 per ton; steel and all other 
essential supplies used in zinc-ore mining are from two to 
five times higher than they were two years ago, and labor also 
is much higher. There being no possible chance for lower 
prices of raw materials it follows that unless zinc-ore pro- 
ducers soon receive better prices for their ore many companies 
will be unable to continue and shut-downs are anticipated in 
every district of the entire field. Labor conditions showed 
considerable improvement through the month. 

Prices for zinc ore were badly upset during the whole 
month, the base being given at the beginning of the month 
at $62 per ton for top grades with the range down to $57 for 
second and medium grades. Inquiry among buyers and 
sellers revealed a wide disparity in figures, the Linden dis- 
trict showing a base of $58 per ton for 60% ore free from lime 
and lead. Cuba City operators reported the same base but 
gave additional figures of an interesting nature, 55% ore sell- 
ing at $44, 50% at $40, 45% at $34, 40% at $30, 35% at $26.50, 
and 30% at $22. 

Lead-ore producers persisted in their campaign of seclusion 
for the entire month, such ore as was sold coming for the 
greater part from the mines of the New Jersey Zinc Co. and 
being delivered to the company's own smelter at Palmerton, 
New Jersey. The regular quotation of $75 per ton for 80% 
material did not apply, therefore, on the lead ore sent East 
and producers not so situated refused to sell their product at 
the prevailing quotation. Production was good considering 
the difficulties milling plants experienced during the greater 
part of the month from frozen intakes, mill reservoirs, and 
pipe connections. The reserve cbnservatively estimated at 
the beginning of the month at not less than 2000 tons all-lead 
concentrate was appreciably increased during December and 
yet operators courageously express the belief that better prices 
for ore are bound to develop before long. 

Shipments of pyrites during the month were restricted be- 
cause of the growing scarcity of cars for prompt loading of 
zinc ore. The increased handling of low-grade pyritic ores at 



refineries is responsible for increased stocks of fine pyrites at 
separating plants and one firm alone reported a reserve stock 
in excess of 2500 tons. It would appear to the close observer 
that there is then held in the field at present not less than 
5000 tons of this commodity. Such sales as were made were 
contingent upon contract arrangements and the price was not 
regarded as satisfactory. 

Shipments of zinc ore from mines to refineries in the field 
and from mines to smelters direct and other ores made during 
December were:

Total 16,498,000 

The recovery of mine run for the month amounted to 20,258 
short tons; total net deliveries out of the field 13,953 tons. 
On distribution the Mineral Point Zinc Co. continued its hold 
on first place with receipts of 169 cars, 6297 tons; Grasselli 
Chemical Co. 137 cars, 5250 tons; Wisconsin Zinc Co. 100 cars, 
3997 tons; National Separators 82 cars, 3468 tons; American 
Zinc Co. 44 cars, 1879 tons; M. & H. Zinc Co., La Salle 40

Benton Roasters 9 cars, 379 tons: American Metals Co. 8 cars. 
366 tons; and Edgar Zinc Co. 6 cars, 201 tons. 

The principal operating firms in this field have had several 
mines under the one management for the past ten years. 
These groups are collectively the source of a major portion 
of the total recovery of zinc ore each month. For December 
the Vinegar Hill Zinc Co. delivered 106 cars, 4272 tons of 
zinc-ore concentrate. The Wisconsin Zinc Co. was a close 
second, delivering to the Skinner Roasters 100 cars, 4047 tons. 
The Mineral Point Zinc Co. was third, shipping from its own 
mines 96 cars, 3680 tons, to Mineral Point. The Frontier 
Mining Co. sent out 78 cars, 3019 tons, but shipments for De- 
cember from this group of producers has been lighter than in 
several months preceding owing to bad roads and to the fact 
that several of its best producers are considerable distances 
from the railroad.

makes wages here higher than ever before. There is no doubt 
whatever ihai the Calumet it Hecla interests would have given 
the workingmen a further increase in pay if they had any 
expectation that the Government would permit a raise in the 
price of copper above the 2SiC. now in vogue, arbitrarily fixed

as stable for the metal used by the Government in munitions 
and for the Allies in their munitions. There was some hope 
that the price would be fixed at 25c. per pound as a number 
of the mines are operating at a close margin. As it is the 
continuation of present wages means the largest payrolls in the 
history of this district and is all the more satisfactory because 
the dividends to shareholders have been cut all the way from 
50 to 300%, and in some of the mines they have been shut off 
altogether. The Calumet & Hecla announcement counts for 
more than one-half of the mining corporation employees of 



this district, 12,000 men in .ill. The other mining companies 
will follow the lead of the old Calumet, so that compensation 
to employees in the Industry upon which this district depends 
will In' as high for the coming six months as ever before and 
tin' production of copper for war purposes will be pushed as 
never before. It is a remarkable thing that every campaign 
for Liberty bonds, for Y. M. C. A. contributions, for Knights 
of Columbus work, and for Red Cross membership has met 
with enthusiastic approval and 
endorsement on the part of the 
miners of this district. There 
are no less than 30 different na- 
tionalities mixed in the cosmo- 
politan make-up of the Michigan 
copper district. Included are 
many technical alien enemies, 
Hungarians, Austrians, Crea- 
tions, Germans, although only a 
comparatively small number of 
the last. They are employed in 
the mines. Their lodges have 
passed resolutions of loyalty to 
the United States, and nobody 
Questions their loyalty. They 
are all members of the Red 
Cross and liberal contributors. 

There is reasonable expecta- 
tion of an increase in output for 
December for the Hancock Con- 
solidated, owing to the installa- 
tion of the storage-battery loco- 
motive. More trammers are 

needed. Electric locomotives 

are used at the Calumet & Hecla 
and subsidiaries as soon as they 
arrive; they are being operated 
on the longest underground 
hauls. Allouez is using five with 
satisfactory results. On the 
Osceola vein at No. 15 two are 
in use; 25 in all will be em- 
ployed; Isle Royale is using 

three. Superior already can 

see the end in sight. This is 
one of the smaller Calumet & 
Hecla subsidiaries, yet it has an 
interesting history in view of 
the fact that the company was 
the first one taken over for man- 
agement purposes, when the 
policy of expansion was under- 
taken by the Calumet interests. 
At the present rate of output, 
450 or 500 tons per month, the 
Superior has less than a year 

and a half in sight. The 

Franklin continues to handle 
1000 tons daily and is hetter 
than breaking even at the Gov- 
ernment price for the output. 
Practically all of this ore has a long tram haul, either by elec- 
tric rope or compressed-air power. 

Production of copper from the Michigan district will be 
230,000,000 lb. for 1917. Exact figures will not be available for 
60 days as smelters usually are from two to four weeks hehind 
mills and mines in output. This estimate is based upon actual 
figures for the first eleven months of the year and estimates 
on December output. This figure is conservative and is just 
5,000,000 lb. below the output for 1916. It is a remarkahle 
record of efficiency, despite high costs, shortage of labor, and

inability to secure deliveries on necessities for mining, mill- 
ing, and smelting operations. No other copper-producing 

district in the world will come as near to normal as the Lake 
Superior district in 1917. This fact is a tribute to the highest 
class of copper-mining employees as well as the good manage- 
ment. Calumet & Hecla alone will produce normal, 77.000,- 

000 lb., compared with 76,762,240 lb. in 1916 and 71,030,518 lb. 
in 1915. Of the group of mines operated under the manage- 
ment of Mr. MacNaughton, as vice-president, the greatest in- 
creases are shown in Ahmeek and Isle Royale. Ahmeek's 
showing for this year is 2S, 600,000 lb., compared with a little 
better than 21,000,000 lb. in 1916 and 21,800,000 lb. in 1915. 
Isle Royale produced, in 1915, 9,342,000 lb., in 1916, 12,412,000, 

and this year 1917 the output will crowd 13,600,000. Allouez 

will not produce up to the normal of 10,000,000 lb., Centennial 
likewise shows a falling off, and White Pine will be below 
1916, but by only a small amount. Osceola Consolidated shows 
the greatest slump in output. It will show 16,300,000 lb., 
3,000.000 short of normal in recent years. La Salle, while a 
small producer, shows a remarkable percentage of increase, 
rising close to 2,000,000 lb. this year. Superior clumps off 
nearly a million. The total for the Calumet & Hecla inter- 
ests for the year will be less than 3,000,000 lb. short of 1916. 
The Mohawk mine, one of the Stanton properties, will show 
12,500,000 lb. Quincy production will exceed 21,000,000 lb., 
while last year this mine produced 21,065,612 lb. Wolverine 
figures for 1917 are 5,200,000 lb. Copper Range three mines 
show approximately 46.000,000 pounds. 

While the production of copper from the three important 
south range producers. Champion, Trimountain, and Baltic, 
shows a falling off of 17% for the year 1917 compared with 
1916, the respective totals being 46,000,000 and 54,747,498 lb., 
this is simply the result of intensive mining. Of this total 
the Copper Range company does not, of course, secure all, as 
the output of the largest producer, the Champion, is divided 
equally with the St. Mary's Mineral Land Co. Quincy con- 
tinues to turn out substantial mass copper with its regular 
run of ore. Regarding the larger masses that have been se- 
cured at the Quincy, there has been some doubt as to the 
ability of any smelter to handle an eight-ton chunk of solid 
copper. The Ahmeek mine frequently gets out masses that run 
10 tons and only last week secured one that ran 114 tons. 
This immense slab was cut from the solid sheet that has been 
one of the big Ahmeek assets for a long period. There was no 
difficulty in handling it in the smelter. The top is taken off 
the furnace and the copper oozed into the furnace much as a 
large piece of ice might he pushed into a water boiler. Cut- 
ting these solid slabs from the mine is a difficult job and re- 
quires men specially trained for the work. They use com- 
pressed-air machines that punch holes in a line a couple of 
inches apart across the solid copper slab; then the holes are 
packed tight with 100% blasting-powder and the powder is 
smeared across the whole row of holes. When it is fired it 

makes a rough break across the solid mass. The output at 

Winona is running better than 500 tons per day with a steady 
improvement in the grade of ore extracted under the present 
system. The tributers are paying the employees a premium 
over their regular wages for the higher-grade ore. the pre- 
mium increasing directly with the proportion of copper. 

While Calumet & Hecla, the old mine, shows slightly better 
output for 1917 than for 1916, it must be remembered that 
this figure includes the output from Tamarack, formerly listed 

as a separate property. Within three weeks the additional 

turbine for the power-plant at Lake Linden will be in use 
and furnishing additional power to the main mine and sub- 
sidiaries as needed. More motors for hauling tram-cars under- 
ground are going into operation this month, some on the 
Osceola lode at the Calumet & Hecla, some at Isle Royale, and 

some at Ahmeek. The Champion continues to be the marvel 

of richness in copper output of any property in the Lake Su- 



perior district. Tonnage is maintained at normal and, while 
the proportion of copper is not going to show as high for 
1917 as it did for 1916, the decline is small indeed. Some 
of the richest shoots of copper in this mine are just beginning 
to be opened. 



COBALT, ONTARIO 

Coxiagas. — McKinley-Darragh. — Peterson Lake. — Ca> i le. 

The silver-mining companies of Cobalt are beginning the 
new year under exceedingly favorable conditions, due to the 
high price of their product. Labor is comparatively plentiful 
and, although the cost of material and labor is considerably 
higher than a year ago, the high price of silver more than 

offsets the increase. The annual report of the Coniagas 

company, which is expected to be issued within the next few 
weeks, will show a total of upward of 1,300,000 oz. of silver 
mined at a cost of a fraction over 21c. per ounce. The price 
of silver during the year 1917 averaged over 81c: it therefore 

follows that the net profit was 60c. per ounce. Excellent 

results are being found at the 400-ft. level of the McKinley- 
Darragh. The method of re-grinding the tailing from the hed 
of Cobalt lake for treatment by flotation has been found un- 
satisfactory, and the new oil-flotation plant is undergoing 
some changes. The rod-mills are being replaced by ball-mills 
and with a return to warm weather the plant will be in shape 

to operate at full capacity. The Peterson Lake company is 

considering the advisability of erecting a mill to treat the old 
tailing-dump of the Seneca Superior. During December ap- 
proximately 102 ft. of underground work was done at the 
Adanac. The zone to the north, the exploration of which 
geologists have recommended, will be reached within the next 
month, and the operation is commanding considerable atten- 
tion. The Mining Corporation and the Nipissing Mines Co. 

are maintaining a heavy yield and appear to be entering into 

a prosperous year. The Castle Mining Co., owning property 

in the Gowganda silver area, has confirmed an arrangement 
with the Tretheway mine of Cobalt whereby the latter options 
the stock of the Castle property. The Castle company has 
500,000 shares in the treasury, on which the Tretheway com- 
pany has an option at 20c. per share, and some 265,000 shares 
outstanding are to be optioned at the same price. The prop- 
erty is adjacent to the rich Miller Lake O'Brien mine and is 
looked upon as a prospect of considerable merit. 

At no time in the history of Porcupine were development 
operations being conducted on a more aggressive scale than 
at present. Work which during the boom days would have 
caused excitement now passes almost unnoticed. Notable 
among recent discoveries are those in the 800-ft. level at the 
Dome, in the 1000-ft. level at the Mclntyre-Porcupine, and in 

the 1400-ft. level on the Millerton claim at the Hollinger. 

The Schumacher company is gradually strengthening its posi- 
tion. The plan of the management to carry the main shaft 
from its present depth of 600 ft. to the 1000-ft. level will 
shortly be done. The new mill is in full operation and giving 
good satisfaction. The Porcupine Crown is developing con- 
siderable ore at the 1000-ft. level. 

The British American Nickel Corporation has under con- 
struction near Sudbury a new electrically-operated smelting 
refinery, which will have a capacity of 2500 tons of ore daily 
and a nickel production of 20,000,000 lb. per annum. The 
smelter will produce a matte carrying 80% copper and nickel 

combined, which will receive final treatment in the refinery. 

The International Nickel Co. is constructing a new refinery at 
Port Colborne at a cost of $4,000,000, which will be in operation 
in a few months. The initial capacity will be 15,000,000 lb. of 
nickel per annum, but it can be expanded in a few years to 
produce 60,000,000 lb. The new plant, according to the com- 
pany, will be able to supply the needs of the whole British 
Empire.

ALASKA 

(Special Correspondence.) — As a result of energetic pros- 
pecting by representatives of the Alaska Treadwell Co. during 
the summer, a molybdenite property situated about SO miles 
from Wrangel has been bonded at Shakan. It is said to be ex- 
tensive, although but little development has been done. Molyb- 
denite is disseminated uniformly through the ore which also 
carries but a small amount of copper. Work of equipping and 
developing has already begun under Peter Johnson, formerly 
foreman of the Treadwell mines. A concentrating plant will 
be erected in the spring. 

Treadwell, December 30. 

ARIZONA 

COCHISE COUNTY 

(Special Correspondence.) — More than $2S1,000 was dis- 
tributed among the employees of the Copper Queen branch 
of the Phelps-Dodge Corporation, the Calumet & Arizona Min- 
ing Co., and the Shattuck-Arizona Copper Co. on January 7, 
in Bisbee and Douglas, this amount coming as bonuses in 
extra checks along with the regular pay checks for the last 
half of December. The miners employed by these companies 
in the Warren district received these checks, according to 
their term of employment, the amounts ranging from $100 to 
$30. All white employees on the surface and underground 
who had been continuously in the employment of the com- 
panies for one year or more received $100, while those who 
had been in the service for six months to one year received 
$50. The Mexicans employed on the surface continuously 
for one year or more received $60, while those who had been 
in the service from six months to one year received $30. The 
amount distributed to the underground and surface employees 
of the three companies in the Warren district totalled $186,250, 
divided among the three companies as follows: Copper Queen, 
$110,000; Calumet & Arizona, $65,000; Shattuck-Arizona, 
$11,250. At the Copper Queen and Calumet & Arizona smelters 
in the Douglas the same bonuses in the form of extra checks 
were paid the smeltermen, the same amounts being given as 
were received in the Warren district. The amount paid in 
Douglas totalled $95,620, as follows: Copper Queen smelter, 
$60,000, and Calumet & Arizona smelter, $35,620. The wages 
paid at the mines and smelters are on a sliding scale, gov- 
erned by the price of copper. With copper at 23Jc. the men at 
the mine receive $5.35 per shift of eight hours, the time be- 
ginning at the collar of the mine-shaft. At the smelter the 
following wages are paid: furnace-men, $5.35; machinists, 
$5.60; converter-men, $5.35 to $5.60; crane-men, $5.60; car- 
penters, $5.60; common labor, $2.30 to $2.60. Announcement 
"has heen made that the companies are working out a per- 
manent time-service bonus plan whereby continuous service 
will receive special consideration. 

Douglas, January 7. 

MARICOPA COUNTY 
(Special Correspondence.) — Development on Empress Copper 
mine 15 miles east of Wickenburg has reached a depth of 400 
ft. The vein is six feet wide and averages $15 gold and 13J% 
copper. The mine is equipped with a 25-hp. hoist and a Sul- 
livan-Foos 70-hp. engine; an electric pump to hoist 40 gal. of 



water per minute is being placed on the 400-ft. level. J. P. 
Hutchinson of Phoenix is president and superintendent. 

The management of the Carmelita Mining & Milling Co., 
with property in the Yuma range, is installing a gasoline hoist, 
Ritz air-compressor, hammer-drills, ball-pulverizer, three con- 
centrating tables, and flotation process, all of which have been 
purchased in Los Angeles through the agency of the Kennard- 
Bierce Engineering Co. In the early days many thousand 
dollars were obtained by the arastra process. There are 17 
claims in the group with more or less development upon each. 
J, A. Marx is superintendent. 

Phoenix, January 10. 

MOHAVE COUNTY 

(Special Correspondence.) — The newly constructed concen- 
tration mill at the Red Cloud mine, 40 miles north of Yuma, 
is proving satisfactory. At 500 ft. the vein is 14 ft. wide and 
from this depth a cross-cut has been driven and a streak of 
high-grade ore found. The mill is of 300 tons capacity and is 
equipped with Hendy crusher, Eggleston ball-mill, and three 
Stebbins dry-concentrating tables. A product of 15 tons into 
one is produced. Cris Engle is superintendent. 

Yuma, January 10. 

A. G. Keating, consulting engineer to the Gold Mining Co., 
expects to commence shipping 100 tons of ore daily by March 1. 
It may require two weeks time to fill up the ore-bins of the 
old Gold Road mill, as they have from 1200 to 1500 tons ca- 
pacity. By March 15 the mill should be treating 100 tons 

daily and bullion should be turned out 30 days later. With 

December partly estimated, it can now be stated that the Oat- 
man district produced only a little short of $2,500,000 in gold 
during 1917. This is more than three times the production of 
1916, and it exceeds by over $500,000 the greatest amount ever 
mined in the district before. The year 1912 showed the high- 
est previous production, according to Government statistics, 

the figures being 1,899,131. The west drift from the 550-ft. 

level of the Gold Road Bonanza shaft has been driven 40 ft. 

from the shaft in commercial ore. The close of the first 

year's operation of the United Eastern sees production main- 
tained at the usual rate. The work of cross-cutting to the 
vein at the lower new level, 1090 ft. below the collar of the 
shaft, is about to begin; from 30 to 60 days may be consumed 

in opening the vein at this level. Exploration of the Tom 

Reed Gray Eagle vein by means of a cross-cut from the 535-ft. 
level of the Aztec vein is now under way, hut several weeks 
will be spent in driving this cross-cut, as the two veins are 

about 400 ft. apart. At a depth of 350 ft. a station has been 

cut by the Record Lode Mining Co. and driving along the vein 

is now in progress. The United Oatman adit has been 

driven nearly 800 ft. on the Ophir vein. A cross-cut to the 
west is also being driven.

YAVAPAI COUNTY 

(Special Correspondence.) — Work at the Jerome-Portland 
has been stopped. The men have been paid off, the pumps 
pilled out of the 500-ft. shaft, and some of the equipment sold. 
J. F. Miller & Co. of Jerome has placed an attachment totaling 

S4100 on the real estate holdings of the Jerome-Portland. 

It is reported that some ore has been discovered in the 1200-ft. 
level of the Blue Bell mine of the Consolidated Arizona Smelt- 
ing Co., which is running higher in gold and copper than the 
ore on the 1600-ft. level. Recent development 2000 ft. south of 
the main shaft of the Blue Bell has opened a 24-ft. orebody at 
a depth of 75 ft. The company plans running a drift on the 

SOO-ft. level southward to open the new strike at depth. 

The Jerome Del Monte has suspended operations for the period 

of the War. Shipments from the Jerome Verde have been 

suspended because it failed to renew the contract with the 
United Verde Extension to hoist 25 tons of its ore per day.

CALIFORNIA 

ELDORADO COUNTY 

The new Chili type of ball-mill is in operation at the Cin- 
cinnati gold quartz mine, situated 11 miles north-west of 
Placerville. On January 9 Jesse W. Taylor, of Fort Worth, 
Texas, accompanied by N. H. Burger, manager of the Cin- 
cinnati mine, and Burr Evans, mining engineer, made an ex- 
amination of the mine and mill. The mine is opened and 
worked by a 300-ft. adit on the vein. At present ore is being 
stoped 50 ft. above the face of the adit from a 16-ft. pay-shoot 
of friable porphyritic material intermixed with particles and 
pieces of quartz, some of which contain high-grade gold-bear- 
ing arsenical pyrite. The entire cost of mining and milling 
the ore is less than one dollar per ton. The mill is operated 
by a 7-hp. gasoline engine. At present about 1J tons per hour 
is put through the mill, but it is expected that this will be 
increased to two tons or better. Mr. Taylor is here to con- 
sult with Burr Evans with the view to interesting himself 
and Texas associates in the mines of this county. 

KERN COUNTY 

The miners of this county have formed an association to be 
known as the Caliente Creek Mining Association, which will 
meet at least once each month with the view of exchanging 
ideas and generally promoting the welfare of the mineral in- 
dustry of the district. C. J. Stoneham, superintendent of the 
Copper-Jap mines, was elected chairman and Joe J. Carroll 
secretary. 

NEVADA COUNTY 

(Special Correspondence.) — An 8-in. shoot of gold quartz, 
assaying $400 to $500 per ton, has been struck on the 900-ft. 
level of the Norambagua mine. Prospecting has been in 
progress over a year at this depth, and arrangements are 
being made to develop the new shoot vigorously, in the belief 
that it is a branch of the main orebody. C. T. Green is super- 

tendent. Good ore has been found in the western end of 

the Golden Centre mine. A short run of the mill recently 
yielded $35,000, according to reports by workmen. Several 
months ago the directors authorized sinking of the main 1000- 
ft. shaft to a depth of 2000 ft. and development of new ground 
is being pushed as rapidly as the water is cleared out. The 
mill is running steadily and the working-force was increased. 

The California mine, near Rough & Ready, is reported 

to be developing well. It is owned by King C. Gillett and 
associates of Los Angeles and has been equipped with an 



excellent plant. — The new vein uncovered in the Sultana 
continues to develop well, and the company is arranging for 
more extensive operations. The strike was made on the 1000- 
ft. level, and, according to reports, about the time the com- 
pany was considering suspension of work. Most of the 

equipment formerly operated at the North Star shaft of the 
North Star mine has been dismantled and numerous sections 
moved to the Central shaft. Use of the old shaft has been 
practically discontinued, but it is kept in repair for safety 
and ventilating purposes. The Central shaft is more than 
6500 ft. deep and splendidly equipped. Development in the 

lower levels has been satisfactory. The 40-stamp mill at 

the Brunswick Consolidated is running steadily; good ore is 
reported at several points. Much new ground has been added 
to the productive area in the past year. 
Grass Valley, January 16. 

SHASTA COUNTY 

(Special Correspondence.) — The Mammoth Copper Co. has 
given up its bond on the Delta Consolidated gold mine, six 
miles west of Delta on Dog creek. The Delta Consolidated Co. 
has sold the steel rails on the 6-mile railroad from the mine 
to Delta to a lumbering company. The 300 tons of steel was 
sold for $60 per ton, or more than it cost when the railroad 

was built in 190S. The Central mine, at Old Diggings, which 

has been idle for years, is being opened up by A. A. Anthony, 
who has become the sole owner. He has given a. lease to 
W. J. Thompson and James W. Holbrook. who are opening a 
good body of gold quartz. A new body of ore has been un- 
covered in the New Year's mine at the Balaklala camp. The 
ore was found by a diamond-drill, and proved by a raise of 
100 ft. from the old workings. The New Year's is a claim 
in the heart of Balaklala ground, owned by the Mountain Cop- 
per Co. On December 24, fire destroyed a four-story bunk- 
house and the boarding-house at the Balaklala mine. A full 
stock of provisions had been laid in for the winter. The loss 
was $40,000. The management believes that the fire was of 
I. W. W. origin. Temporary quarters were soon provided. 
The mine was shut-down for only two days. 

Redding, January 5. 

The Mountain Copper Co. is doubling the capacity of its oil- 
flotation plant at Minnesota station, midway between the Iron 
Mountain mine and Keswick. It is not building a cyanide 
plant, as currently reported. The first flotation-plant was 
built three and a half years ago, and was doubled in capacity 
two years later. The enlarged plant will have a capacity of 
1000 tons per day. Grading for the site is under way. The 
company is hampered for the want of material, as it can only 
get lumber and other building products at the pleasure of the 
Government. Work will be rushed as rapidly as war condi- 
tions will permit. The Mountain Copper Co. was the first 
mining corporation in Shasta county to use oil-flotation. 

TULARE COUNTY 

(Special Correspondence.) — During 1917, 1970 cars of mag- 
nesite, worth approximately $2,400,000, was shipped from the 
Porterville district. As each car averages about 45 tons this 
makes a total of nearly 90,000 tons. Of this amount about 
50.000 tons was of the calcined ore, worth approximately 
$2,000,000. The remaining tonnage was shipped in the raw 
state and is valued at about $400,000. Recently Federal au- 
thorities made a special request for data on the magnesite out- 
put of this district last year and the prospects for the amount 
available in the future. It is probable these data are being 
sought in line with other war preparations of the Government, 
as the output of the steel plants is in a large measure de- 
pendent on the output of magnesite. Owing to its highly re- 
fractory qualities magnesite is used extensively for linings 
of furnaces where a high temperature is maintained.

PITKIN COUNTY 

(Special Correspondence.) — On January 8 the stockholders 
of the Hope M. M. & L. Co. held its annual meeting. A canvass 
of the stock at the meeting showed that 67,715 shares were 
represented in person or by proxy. The following officers 
were unanimously re-elected: Charles O'Kane, president; 
James W. Hetherly, vice-president; Harold W. Clarke, sec- 
retary; John B. Stitzer, treasurer; and Charles O'Kane, 
Henry Turley, Albert Peterson, James W. Hetherly, and John 
B. Stitzer, directors. In his report to the meeting, Mr. O'Kane 
stated that during the past year the main adit had been ad- 
vanced 1047 ft. at a total cost of $15,275, making the average 
cost per foot $14.5S. The advance made in the breast varied 
during the year, some months showing better results than 
others. Following the advice of Messrs. Tower and Foote, who 
recently made an examination of the Hope properties, the 
course of the Annie cross-cut has been turned to due east. 
In making this turn, the drift cut 100 ft. of porphyry and a 
number of low-grade ore deposits, assaying as high as 22 oz. 
silver, 14% lead, 2% copper, and 22% zinc. The deposits, how- 
ever, would not average as high and could not he handled 
profitably, but their presence is considered to be a favorable 
indication of richer bodies ahead. One large shoot was 75 ft. 
thick. The question of increasing the capital stock from 
100,000 to 150,000 shares came up before the meeting and was 
passed without a dissenting vote. The additional capital is 
required to complete successfully the work now under way. 
The prospects of the enterprise are regarded as bright, and it 
is believed that large bodies of shipping ore will be found 
during the year.

TELLER COUNTY 

(Special Correspondence.) — The December production from 
mines of the United Gold Mines Co. was 66 cars, containing 
2500 tons of an average value of $21 per ton, and a gross 
bullion value of $52,500. The production from the several 
properties was as follows: Trail mine, Bull hill, Anderson and 
Benkelman lease, 43 cars; J. L. Wilson lease, 12 cars; W. P. 
H. mine, Ironclad hill, shipped by the W. P. H. Leasing Co. of 
Cripple Creek, 7 cars; Bonanza, Battle mountain, operated 
under lease by the Granite Gold Mining Co., 2 cars. This ore 
assayed close to 3 oz. gold per ton. Wild Horse mine, Bull 
hill, 2 cars mined and shipped on company account. The 
Wild Horse company on December 20 paid a 1 cent dividend 
amounting to $40,090 from accrued royalties paid into the 

treasury by lessees during the past year. The output from 

properties of the Elkton Consolidated Mining & Milling Co., 
on Raven hill, for December amounted to 24 cars, or 850 tons, 
including dump shipments and the average value held close to 
one ounce gold, dump ore running as high as $17.50 per ton. 
The company resumed operations during the month and ship- 
ped two cars of mill ore. George E. Collins of Denver, manager 
of the Mary Murphy mine, operating the Tornado mine of the 

Elkton company, shipped 4 cars of 1-oz. grade. The Cripple 

Creek Deep Leasing Co. and its sub-lessee F. T. Caley, operat- 
ing the Jerry Johnson mine on Ironclad hill under lease from 
the Jerry Johnson Mining Co., produced 455 tons of mill ore, 
averaging $21 per ton, during December. Two cars from the 



tease, taken between 60 id Ton it., brought $57 and 

$60 per ton, respectively. Edwin Gaylord. of Cripple Creek.

SHOSHONE COUNTY 

The third dividend of 5c per share has been declared by 
the Hecla Mining Co. Until November last the company was 
paying 15c per share monthly. Lower prices for metals and 
the heavy Federal tax have caused the reduction in dividend 

rate. For the first three weeks of operation $12,000 per 

week is the reported amount cleaned up by the Yukon Gold 
Mining Co., which recently began placer operations on 
Pritchard creek. The company is working the stream along 
which gold deposits were first discovered 35 years ago. Some 
large nuggets have been found. The company is a Guggen-

taken out during the first ten months of 1917, according to 
report of Raymond Guyer, manager. The mine was idle in 
November and December. 

No dividend has been declared. The records, when com- 
pleted, will probably show that the profits have been ex- 
pended in development work which has been expensive be- 
cause of higher cost of supplies and labor. Resumption of 
work is expected at an early date. 

MISSOURI 

JASPER COUNTY 

A concentrating plant is slowly being built by the Pleasant 
Valley Mining Co. on its lease about three miles south-west of 
Carthage. A good part of the equipment already is in place 
and more is being added, with the idea of having the plant 
complete by spring. The Pleasant Valley mine has been a 
good producer during the past year, operated merely as a 
hand-jig property. There has been a battery of nine of these 
hand-jigs, however, and a carload of ore has been made on 
the average and when things have been running well about 
every ten days. Operations are conducted at a depth of 100 
ft., and the ground is well opened, there being two shafts in 
use. The concentrate is particularly satisfactory, being lead 
free, less than 1% in iron, and usually showing about 62% 
metallic zinc. The equipment at the plant, besides the hand- 
jigs, already includes a 90-hp. gas engine, a set of 30-in. rolls, 
a 14-in. crusher, and rougher and cleaner jigs are now being

built. The company is made up of J. H. Millard, H. H. Hoff- 
man, and W. M. Graves of Carthage, and W. S. Pitt of Minne- 
sota. Mr. Graves is superintendent. The company is operat- 
ing this mine on a 20-acre lease of the Freer land, but it has 
in addition leases on the Douglas and St. Louis land, for a 
total of 100 acres. 

LAWRENCE COUNTY 

Recent drilling operations on the Grier land, west of Aurora, 
have been decidedly successful and it appears that a new 
richly-mineralized tract is about to be opened there. To date 
eight holes have been put down, five of which have showed 
excellent mineral. The last hole went into ore at 135 ft., and 
was still in it at 155 ft., indicating a 20-ft. face. The other 
holes showed ore at approximately the same level and for the 
same depth. The development work is in charge of J. H. 
Grier, owner of the land. After the drill prospect work is 
completed he intends to lease the property or develop it him- 
self. 

NF.VADA 

ESMERALDA COUNTY 

(Special Correspondence.) — The Kewanas company is pre- 
paring for more comprehensive work in the northern and 
southern ends of the property. In the latter area connections 
have been made with the shaft of the Jumbo Junior, and a 
series of raises will be driven to prospect the main orebody. 
This has yielded some rich ore in the Jumbo Junior and ore 
of shipping and milling grade in Kewanas territory. In the 
northern section the more important work is proceeding 800 

ft. north of the station. Occasional shipments are being 

made from the Great Bend to the sampler of the Western Ore 
Purchasing Co. The product comes from the intermediate 
drift below the 160-ft. level, where two feet of $100 ore accom- 
panies the lower-grade material. From the 300-ft. level a 
drift is nearing the old Lockhart lease shaft, where milling 
ore was exposed when the lease ceased work. It is the plan 
of the management to eventually improve the small mill and 
operate the plant on the medium-grade ore in sight. Free- 
milling ore assaying $25 to $90 per ton is being broken in an 
intermediate drift above the 100-ft. level of the Blue Bull. 
The vein occurs in the Pig claim and is narrow. A winze is 
down 125 ft. on this vein and driving from the 250-ft. level 
will start shortly for the purpose of developing ore at this 

depth. Conditions at the Spearhead are improving. New 

work on the 250-ft. level has opened milling ore near the 
Wheeler shaft, and on the 910-ft. level north and south drifts 
are exposing milling-grade ore. From the east cross-cut on 
the 320-ft. level of the Cracker Jack drifts are prospecting two 
promising veins, showing scattered bunches of gold and silver- 
bearing ore. 

Goldfield, January 14. 

During November the Goldfield Consolidated produced 16,350 
tons of ore at a profit of $S3S0, and 14,459 tons of mill-tailing 
was treated at a profit of $1981. Development to the amount 
of 858 ft. was performed at a cost of $7.74 per foot. 

LINCOLN COUNTY 

(Special Correspondence.) — The Virginia-Louise Co. has 
placed orders for a large hoisting-engine and other machinery, 
and plans to start extensive operations in February. The 
management reports that considerable ore of profitable grade 
is exposed. The apex suit of the Prince Consolidated against 
the Virginia-Louise will be called in the Federal Court at 
Carson City shortly; both parties have retained eminent 
counsel. The Virginia-Louise recently brought suit for dam- 
ages against the Prince Consolidated, alleging defendants had 
extracted ore unlawfully from its holdings. A decision by 
Judge Averill of Tonopah is expected soon. The Raymond- 
Ely West Mining Co. is contemplating early resumption of 
activities. The property adjoins the Amalgamated-Pioche and 



Greenwood mines, and the Greenwood Leasing Co. is en- 
deavoring to secure a long-term lease. It is also reported that 
the company may operate extensively on its own account. 
Simon E. Bamberger, governor of Utah, E. A. Vail, M. B. 
Johnson, W. E. Harrison, and other Salt Lake capitalists are 
interested.-* — Much new work is proceeding at the Prince 
Consolidated, Amalgamated-Pioche, and other properties in 
this field. Late developments in the Prince Consolidated have 
been particularly encouraging, according to reports from the 
mine. This property has paid $500,000 in dividends to date. 
Pioche, January 13. 

NYE COUNTY 

(Special Correspondence.) — Milling and shipping ore have 
been developed on the 200 and 300-ft. levels at the Mayflower 
mine, and 1400 ft. north-west of the shaft a promising vein 
has been uncovered near the surface and opened to a depth 
of 35 ft. For the entire distance the vein consists of excel- 
lent milling ore, with portions carrying a high gold content. 
Arrangements have been made for extensive work on the first, 
second, third, and fourth levels, and from the tBird a drift 
will be extended to connect with the Starlight shaft. The 
mill is to be overhauled and improved, preparatory to steady 
operation. The management reports a large tonnage of profit- 
able ore exposed. The property is owned by the Consolidated 
Mayflower Mines Co., of which W. J. Tohin is president and 

general manager. The Sunset Mining & Development Co. 

is devoting particular attention to the Denver mine, where 
good ore has been opened on the 450 and 500-ft. levels. Abun- 
dant water for the mill has been secured and the management 
expects to operate the improved plant steadily this year. The 
holdings include the Denver, Tramps Consolidated, and Sunset 
groups. The Pioneer Consolidated Co. is completing nego- 
tiations for a steady supply of power for the mill. A large 
tonnage of milling ore is in sight, but for several months 
the mill has been idle because of inability to secure econom- 
ical electric power. Underground work has proceeded steadily 
and an extensive reserve of profitable ore is available for 

mining. Leasing is active at the Montgomery-Shoshone, 

Indiana, and other properties. Arrangements have been made 
for early resumption of work on the New Year, Gold Bar, and 
several others. Many of the companies have been recently re- 
organized on an assessable basis. 

Pioneer, January 5. 

WHITE PINE COUNTY 

(Special Correspondence.) — The Nevada Consolidated Cop- 
per Co. is running smoothly and turning out its usual tonnage 
of ore. Owing to the continued shortage of coal, fuel-oil is 
being used in the reverberatories and converters, though at a 
much greater daily cost than coal. The new railroad cut-off 
across Steptoe creek, which materially reduces the grade to 
the smelter, is completed. On account of the reduced grade the 
ore trains are hauling thirty 60-ton cars with the same loco- 
motive and crew that formerly hauled 21 cars of 55 tons 

capacity. The Consolidated Copper Mines shut-down its 

mill on January 1 and laid off about 200 men. It treated an 
average of 800 tons per day during the last month. The mill 
while metallurgically efficient was so poorly constructed that 
a thorough overhauling has become necessary, and, as there 
is a shortage of ore, the present time is convenient for mak- 
ing the repairs. But the main cause of shut-down is for want 
of ore to keep the mill supplied. For the past two months the 
Nevada Con. has mined and delivered at its mill from the 
Giroux Ora claim some ore continuously. It is planned to de- 
velop the mine while the mill is closed, and thus ensure a 

supply of ore when the repairs have been completed. The 

county road has been changed from Keystone to the Copper- 
mines property, which allows the company to put in a retain- 
ing dam to impound the tailing that has been running down 
by Robinson creek. The Ward mine is shipping 25 tons

There has been a dispute over title of pan of the ground and 
an Injunction against shipping was granted; but this was re- 
cently settled, by allowing one en' the parties to mine and ship 
and deposit in the hands of the Court $11! per ton until SUCb 
a time as the title of the ground in dispute shall he settled by 
the courts. The Muncy Creek property and the Lucky De- 
posit at Aurum, are continuing to ship copper ore. The county 
commissioners allowed the expenditure of $11)0 to gravel and 
grade the road for trucks to a new spur put in on the Nevada 
Northern, ahout four miles south of Cherry Creek station, thus 

shortening the haul by ahout 30 miles. Most of the lessees 

and outside work is closed for the winter. 
Ely, January 3. 

NEW MEXICO 

SOCORRO COUNTY 

(Special Correspondence.) — The production for the district 
for 1917 was 12,590 oz. gold and 732, 5S1 oz. silver, or at present 

prices $903,000. The principal operating companies were 

the Socorro Mining & Milling Co., the Mogollon Mines Co., and 

the Oaks Co. On Octoher 26 fire destroyed the mine plant 

and upper portion of the Socorro mill. These are being re- 
placed rapidly. A large part of the material is now on the 
ground and it is expected that the plant will be in operation 
early in the summer. Among the important developments of 
this company has been the cutting of a large body of good ore 
on the 1100-ft. level and new orebodies in the Johnson and 
Champion mines. The Mogollon Mines Co. completed its new 
900-ft. shaft, has the drifts well started on lower development, 
and has largely increased the available ore-reserve during the 

year. Its 150-ton mill has run steadily to capacity. The 

Oaks Co. has increased operations during the year. In March it 
took over the Maud S. mine, found ore within 30 days, and has 
been shipping daily to the mill since. In June the Deep Down 
mine was acquired, the Central shaft re-timbered, and a head- 
frame and hoisting-plant erected. Ore has been opened west 
of this shaft, which is being developed and shipped to the mill. 
Development and production have been continued at the 
Eberle and Clifton mines, the other two properties of the 
Central group, which are to be operated through the shaft on 
the Deep Down mine. Work was started on the Pacific mine 
in December and arrangements are being made to continue 

regular production. The Deadwood shaft is being un- 

watered, material is being delivered, and this property will no 

doubt be in operation in the near future. The main adit on 

the Iron Bar group is being driven to cut the ore found in the 

upper workings. The year's operation at the camp has been 

favorable. While the fire at the Socorro mill reduced the pro- 
duction of the district to a marked degree the developed new 
ore in the deepest workings and the new properties opened 
point to a much increased production for 1918. 

Mogollon, January 9. 

OREGON 

JACKSON COUNTY 

(Special Correspondence.) — Since the winter rains have set 
in, the copper mines in southern Oregon, which have long 
wagon-hauls, are reducing their shipments of ore and are de- 
veloping for record shipments next season. The Blue Ledge 
has 60 men employed and is shipping 1000 tons per month, 
while the Queen of Bronze has 40 men employed and is ship- 
ping 1200 tons per month, and the Waldo has quit shipping 

and has 10 men employed developing. O. C. Runnels of 

Seattle, representing people of that city, has purchased the 
Utah group of quicksilver mines, 12 miles north of Gold Hill, 
as well as the Samuel Bertleson group of adjoining claims, and 
intends to combine these properties. These mines are con- 
tiguous to the Chisholm group of mercury mines, which is 



equipped with furnaces. Machinery is being ordered to equip 
these new mines and representatives of several machinery 

companies are on the ground to arrange the final details. 

Tony Ross and Lawrence Wltsette of Gold Hill, who have a 
lease on the Reynolds copper mine six miles west of Waldo, 
are making considerable progress in development work. Recent 
assays show that the copper ore near the surface runs 10 oz. 
in silver per ton and some gold. This property Is eight miles 
west of the Queen of Bronze copper mines and within half a 
mile of the Grants Pass-Crescent City highway. Five veins, 
from 5 to 20 ft. wide, run through the property at an eleva- 
tion og 2600 feet. 

Gold Hill, December 31. 

(Special Correspondence.) — O. C. Runnalls of Seattle, who 
recently acquired the Utah and Bertleson groups of cinnabar 
mines, 12 miles north of Gold Hill, for Seattle investors, will 
incorporate a company with a capital of $600,000 and equip 
the properties with a mercury-reduction plant of 100 to 200 
tons capacity. A power-line will be erected from the C-0 
Power Co.'s line in the Beagle district, five miles from the 
mine, and electric power will be used in operating. Samuel 
Bertleson of Beagle will be the local manager temporarily. 

Gold Hill, January 5. 

TEXAS 

BREWSTER COUNTY 
(Special Correspondence.) — The Marfa & Mariposa Mining 
Co. has lately sold all its interests, mine, two 12-ton Scott 
furnaces, and about 2000 acres of cinnihar-bearing land. This 




PART OF TEXAS 

mine was discovered by Thomas Golby and G. H. Normand 
in 1S97 and began to produce quicksilver in 1899. For several 
years it turned out about 400 flasks per month and paid over 
$500,000 in dividends. The rich ore was found between the 
massive lime and an impervious clay, in one instance a 
'kidney' was taken out just below the surface of the ground 
weighing 45 tons; many smaller 'kidneys' were found. In 
1909 these rich surface deposits began to be more difficult 
to find and as no work had been done on the low-grade fissure 
veins in the massive limestone, in which the cinnabar was 
found in banded calcite, it was found impossible to run at a 
profit at the low prices then prevailing, so the mine was closed. 
In 1916 it was leased to the late superintendent, A. Newell, 
was re-opened, and has been steadily producing ever since 
with a small force of men and only one furnace operating. 
The Chisos mine is producing 500 flasks of murcury per 
month. The Big Bend, the Texas Almaden, and other mines 
are also producing quicksilver and the prospect for a still 
larger output of mercury is encouraging.

duced 70.000 lb. of copper in the form of a concentrate running 
32' , copper. With the added improvements it is estimated that 

wide and assays from 4 to 5':i of copper. The orebody struck 

on the Noonday mine recently has been followed for 40 ft., 
according to a report from Kaslo. It has a width of eight feet 
throughout. More than a foot of it is of a shipping grade, the 
remainder being concentrating. The strike was made at a 
depth of several hundred feet, at a point near the line of the 
Noonday and the Consolidated Mining & Smelting properties. 
The drift is proceeding into the Noonday from the direction of 
the Consolidated.

(Special Correspondence.) — During the month of December 
there was shipped through the Douglas port of entry 317 cars 
of Mexican-mined ore and concentrate, having an estimated 
value of $2,7S5,000, as compared with 354 cars in November 
having an estimated value of $2.S73,600. The number of cars, 
points of origin, and tonnages are as follows:

Total 317 12,490 

The shipments from Nacozari were composed mostly of cop- 
per-silver concentrates from the concentration plant of the 
Moctezuma Copper Co., which is situated at Nacozari. These 
concentrates were treated at the Copper Queen smelter at 
Douglas. The shipments from El Tigre were composed of 
concentrates from the concentration and oil-flotation plant of 
the Lucky Tiger Combination Co., the shipping point being 
the station of Esqueda, on the Nacozari railroad. These con- 
centrates are treated at the El Paso smelter. The Promon- 
torio mine is owned by the Phelps-Dodge Corporation, the ore 
carrying principally copper and silver. The mine is situated 
in the district of Moctezuma, about 100 miles south of Naco- 
zari, and the ore is shipped to that point by wagon and mule- 
back transportation.

SPAIN 

PROVINCE OF VIZCAYA 
At a joint meeting of the shareholders of the Altos Homos 
de Vizcaya and those of the Hulleras del Turon an agreement 
was reached for the purchase by the Altos Hornos of the coal 
mines in Asturias, now owned by the latter company. This 
purchase follows a lengthy examination of the Turon coal 
mines, and extensive tests of the coking quality of the coal. 
The price is said to be 20 million, pesetas, or approximately 
$4,000,000, which is six times what the mines would have 
brought three years ago, but the great Iron and steel opera- 
tions of the Altos Hornos is relieved from uncertainty of supply 
and exorbitant costs of its needed fuel by taking over these 
Asturian coal properties, even at such a figure. The mines of 
Turon produced 240,000 tons of coal in 1916, and has developed 
at a faster rate than any other coal property in Spain.

Silver has undergone very little fluctuation during the past week and is 
now quoted at 91 %e. per ounce. 

Samuel Montagu & Co. says: The Transvaal gold output for November 
amounted to £3,070.426. as compared with £3.326,253 in November 1916 
and £3,191.279 in October 1917. The total up to the end of November 
is only £35,255,282, compared with £36.19o,229 during the same period 
in 1916. 

The Shanghai exchange continues firm; possibly there is some connection 
between this strength and the approach of the Chinese New Year, which 
falls on February 11. On December 12 the official rate. 4s.3d., the high- 
est received in recent years, approximates within a fraction the point at 
which silver could be shipped at a profit from San Francisco, but it 
should be remembered that silver transactions of this character need a 
license from the United States government. No fresh news has come to 
hand with regard to the projected purchase by the British and American 
governments: pending some definite details the market remains somewhat 
inert. It is proposed in France to demonetize silver coin bearing the 
effigy of Napoleon HI crowned with laurel. The object in view probably 
is to extract the large quantities of such coin now hoarded, to re-coin pieces 
with a new die from the metal thus made available, and then issue them 
as required. It is anticipated that by this means the need of purchasing 
fresh silver for coinage will be reduced.

There is no market in New York at the present moment for spot tin as 
no material is to be had at any price. Straits tin for shipment is quoted 
64 to 65c, while Banea tin, of which some is said to have been sent by 
express overland, is reported sold at 70c. per pound. However, the tin 
position is exceedingly difficult at the present moment and is practically a 
sellers market. 



Charles Hardy says: The past week has seen business started for the 
new year in tungsten ore. and while most of the business was done in 
off-grade ore, some high-grade ore was sold at prices ranging from $24.50 
to $25 per unit. The business in off-grade ore was quite considerable and 
cleared out a good many lots which had been on the New York market 
for some time. The business, however, still meets with a lot of difficulty 
as it is hard to get ore sold on account of freight conditions in New York. 
As soon as shipments can be made with more regularity, the business in 
tungsten should improve. Business was also started during the past week 
in molybdenite at unchanged prices of $2.25 to $2.30 according to grade. 

The antimony market remains non-existent. First hands decline to make 
prices believing that ultimately the market will recover and material in 
second hands which can be had at concessions is not sold as buyers are 
prominent by their absence. 

Manganese remains unchanged with the January schedule at $1.20 
delivered at the furnace for high-grade ore. 

High-grade chrome ore is still quoted at 90c. per unit, f.o.b. shipping 
point, and small business has been reported. 

The magnesite market remains practically the same. A few inquiries, 
however, are in the market for small lots but the market has not shown 
the expected strength as yet. 

California virgin mercury has dropped to about $120 per flask of 75 lb. 
net, while Mexican is quoted around $115 for spot material.

Eastern Metal Market 



New York, January 9. 

The markets are all quiet and do not present any unusual 
features. Readjustment of accounts and the appraisal of stocks 
explain in part the dullness. 

Copper is moderately active at the Government prices. 

Tin is nominal, high, and still scarce. 

Lead is firmer and stronger in tone at higher levels. 

Zinc is again lifeless at unchanged prices. 

Antimony refused to be excited and continues to sag. 

Unprecedented low temperatures in the East and blizzards of 
large proportions in the West have seriously interfered with 
pig-iron production, and have added to the difficulties already 
present because of railroad congestion. Some steel plants are 
operating at only 50 to 75% of capacity. The industry has 
never been so badly crippled. December pig-iron output was 
low (only 2,882,919 tons) or 92,997 tons per day, against 
3,205.794 tons, or 106,859 tons per day, in November. The rela- 
tion of supply and demand is secondary to Government price- 
fixing. An important question for buyers to consider is: I£ 
there are new prices April 1, will they apply to deliveries 
carried beyond that date, even though contracted to be deliv- 
ered in the first quarter? They will, according to reliable 
sources. 

COPPER 

Government demand for copper is reported as becoming 
larger in volume as the weeks go by and this is also true of 
that of the Allied governments. Domestic manufacturers, 
working more or less directly for the Government, are also buy- 
ing more metal. There seems to be a good demand from wire 
mills. The volume of all of this business is large and it is 
going at the regulation Government prices of 23.50c. for car- 
load lots or more, and at 24.671c. for less than carload lots, 
with every prospect of sufficient copper to meet all needs. 
Nothing more is heard of a change in the fixed level, and it 
seems assured that this subject will not come up again for 
some time. The jobbers report that they have frequent re- 
quests for copper at 23.50c. because the conditions under which 
they have taken certain Government orders stipulate that they 
must not pay more than 23.50c. for the copper they use. In 
such cases, the jobbers have had to refuse the business at less 
than 24.67*c How such small orders are being handled no one 
seems to know unless the Copper Producers' Committee is tak- 
ing care of just such small business on Government account. 
One jobbing dealer in New York states that he is doing a good 
business at 24.67Jc. for general consumption. There is some 
talk that the fuel scarcity, combined with railroad congestion, 
may lesson output at refineries, but only time can answer this. 
The output of refined copper from primary sources in 1917, 
according to preliminary figures of the U. S. Geological Survey, 
just issued, is estimated at 2,362,000,000 lb., compared with 
2,259,000,000 lb. in 1916, and 1,615,000,000 lb. in 1913. 

TIN 
A small lot of Straits tin was sold at 80c, New York, on 
January 2 but this is the only transaction noted in many 
weeks. There is no spot market, and quotations are entirely 
nominal at about 85c, New York, with no prospect of the acute 
scarcity being relieved in some time. There has been in the 
last two weeks a big decline in the London market which 
reached its climax about January 3, which probably explains 
the 80c sale referred to. There is no other explanation. Since 
then the London market has advanced suddenly, due perhaps 
to permit negotiations, though the real reasons are not known 
here. On January 7 the London quotations for spot Straits 
was £282 per ton, as compared with £272 on January 3 and 
£309 10s. on December 21. Recently in New York a few buyers 



got their courage up and went into the market, buying in two 
days an estimated tonnage of 200 to 300 tons of futures, mostly 
Straits, with some Banca and Chinese included. This is a 
decided improvement over recent weeks. The rank and file of 
purchasers, however, are still refraining from purchases, pre- 
ferring to wait until conditions are more settled. Arrivals to 
January 3 inclusive have been 460 tons. 
LEAD 

After many weeks of practically one level the lead market 
has advanced, due to a change in the quotation of the leading 
interest. The American Smelting & Refining Co. on January 3 
raised its New York price Jc. per lb. to 6.50c, New York. This 
was followed on the next day by the independents who ad- 
vanced their price to 6.70c, New York, or 6.55c, St. Louis. 
The reason for the advance by the Trust is generally conceded 
to be that because Government purchases are being settled on 
the average St. Louis price and because its New York price was 
lower than the St. Louis, an advance was proper. The result 
of the action has been to make the tone of the market stronger 
and firmer. Business, however, has been only of moderate 
proportions, due to a lack of sellers as much as anything. Spot 
lead is held at 6.75c to 7c, New York. 
ZINC 

The market has relapsed into its former lifeless condition 
and it is not strong. The prevailing quotation for prime 
"Western for early delivery is 7.62i to 7.75c, St. Louis, or 7.871 
or 8c, New York, at which levels a little business has been 
done, but it is not likely that the larger producer would be 
willing to seriously consider a large inquiry at these levels. 
It is understood that the 4000-ton inquiry for grade C for the 
Army's use has not been let. The bids on these were believed 
not to have been numerous, but it is the impression that the 
Government has been able to secure all it needed at the quota- 
tions obtained on the 1000-ton purchase for the Navy, referred 
to in previous letters. The expectation is that the U. S. Geo- 
logical Survey's preliminary statistics on the 1917 output of 
zinc, which will be out any day now, will show this to have 
been not very different from the 667,456 tons produced in 
1916. Exports are estimated at slightly in excess of those for 
1916 when there were 206,000 tons. One estimate puts the 
deliveries into consumption at about 400,000 tons in 1917, which 
is 58,000 tons less than in 1916, but larger than 1915 or any 
other previous year. Although weather and railroad condi- 
tions are interfering with the receipts of metal from the West, 
stocks seem sufficient here. 

ANTIMONY 

The spot market is lifeless at 14.50 to. 14.75c. per lb. duty 
paid, New York. Considerable competition is anticipated for 
an expected Government inquiry for 200 to 300 tons for March- 
April delivery. 

ALUMINUM 

Virgin metal, 98 to 99% pure, is held at 36 to 3Sc, New York, 

for early delivery with the market quiet. Sales are reported 

at 37 to 38c. The Aluminum Company's contract price for 

ingots so far for 1918 is stated as unchanged at 38c. per pound. 

ORES 

Tungsten: Both high and low-grade ore has been sold at 
$24.50 to $25 per unit in 60% concentrate in the last week. 
Business is being more or less interfered with by the weather 
and freight congestion. Perro-tungsten is obtainable at $2.35 
per lb. of contained tungsten. 

Molydbenum and antimony: Molybdenite is unchanged at 
$2.25 to $2.30 per lb. MoSn, depending on the grade and some 
sales are reported at these levels. Antimony is unchanged 
with the market nominal.

INFORMATION FURNISHED BY MANUFACTURERS 



A NEW LEYNER MACHINE 



The modern hammer-drill, using hollow drill-steel and air 
or water to expel the cuttings from the drill-hole is now the 
rule rather than the exception in practically all rock-drilling 
operations. There is considerable carelessness in the matter 
of keeping the hole in the drill-steel open. Wholly or partly 
plugged steels prevent proper functioning of the drill, the 
drilling-speed is retarded, water-tubes are bent or broken, and 
time is lost in tinkering or, as often happens, the drilling 






LEYNEB SHANK AND BIT-PUNCH 

gang is idle while someone makes a trip to the shop after 
another drill-steel or water-tube. To relieve this condition 
the Ingersoll-Rand Co. has developed and is placing on the 
market, as an auxiliary to the 'Leyner sharpener,' a new 
device, the Leyner shank and bit-punch. This compact and 
simply constructed machine consists principally of a cast-iron 
pedestal, at the top of which are bolted the clamping and 
punehing-cylinders and apparatus. The drill-steel is clamped 
by two jaws brought together by the movement of a pinion, 
operated by the clamping-cylinder through the medium of a 
rack on the extended piston-rod. The heat-treated steel 
punching-pin is attached to the piston of a punch-cylinder, 
and in such manner that it may be readily removed should 
occasion require. The front head of the punch-cylinder is 
provided with a clearance space around the punching-pin so 
that, on the extreme reverse stroke, air is exhausted against 
the heated pin, effectually cooling it. The maximum stroke of 
the punch is 6 in. An adjustable stop for the drill-steel is 



provided to regulate the distance to which it is desired to 
have the pin penetrate. The standard punching-pin is ft in. 
diam. for a distance of 2 in. from the end, and § in. lor the 
remainder. The operation of the machine is controlled by a 
single lever moving in a T-slot. A downward movement 
clamps the steel, and a further side-movement operates the 
punch. The operation of the control-lever locks the clamp- 
jaws before the punch can be brought into action. In like 
manner the punching-device must be in a neutral position 
before the clamp-jaws can be opened. This safety feature 
prevents action of the punch before the steel is firmly clamped 
and in perfect alignment. It will be noted that all moving- 
parts are protected from dirt, grit, and damage, by tight- 
fitting covers; likewise the operator is guarded from injury. 
The Leyner shank and bit-punch occupies a floor-space 22 by 
44 in. and weighs 400 lb. A plank support is the only founda- 
tion needed. 



ALBANY GREASE 



Fifty years ago the firm of Adam Cook's Sons was in- 
corporated as the Albany Lubricating Compound & Cup Co. in 
Albany, New York. The firm was founded by Adam Cook. 
The history of Adam Cook's Sons is the story of the growth 
of Albany Grease' and that is the record of grease lubrication 
from its infancy up to the present time. Prior to 1S6S, oil 
was the only practical medium by which lubrication could be 
secured on mechanical work. Lubrication in those days was 
cOstly and not efficient. ' The stumbling block in oil lubrica- 
tion was the exceedingly great amount of attendant waste. 
The trouble was the inability to keep a liquid in some sort of 
a container so that it would not run off or leak out until it 
had accomplished its object and until every lubricating atom 
in it was consumed in service. Adam Cook realized that it 
was highly improbable that any device could be secured to 
give the needed relief, and he selected the lubricant itself as 
the thing to be improved. 'Changed,' is the word that ex- 
presses what Adam Cook did, for in 1868 there was put on 
the market Albany lubricating compound, now familiarly 
known all over the world as Albany grease. That name was 
given to Albany lubricating compound by the engineers of the 
country. The point was willingly conceded, and soon the 
compound was re-christened 'Albany grease,' and has ever 
since been known by that name. 

A small plant in Albany was erected at first, but within four 
years this became too small. In 1872, larger quarters were 
secured on the river front at 231 "West street, New York City. 
Here was thought to be ample room for growth, but soon these 
quarters were outgrown, and in 1SS1, only nine years later, 
the business was moved again to larger quarters at 313 West 
street. As the business grew by leaps and bounds additions 
were made to the original building by the purchase of neighbor- 
ing warehouses and the Albany plant soon ran through the 
entire block from West to Washington street. Despite the 
room available, the need of concentrated methods of produc- 
tion and the assembling of all departments presently made 
itself felt. In order to take advantage of the latest manu- 



22

facturing methods, it was decided to bring into closer rela- 
tions all the various departments of the business under a single 
' roof. After a stay of 30 years, the West and Washington street 
plant was abandoned, and the modern commodious plant at 
70S-10 Washington street was placed in service. 'Albany 
grease' is celebrating its 50th anniversary and is receiving 
congratulations from an army of satisfied users. 



COMMERCIAL PARAGRAPHS 



NEW ORGANIZATION FOR LITTLE GIANT 



After an existence of nine years as a department of the 
Chicago Pneumatic Tool Co., the motor-truck interests of the 
company were, on January 1, taken over by a new organiza- 
tion known as the Little Giant Truck Co. From small be- 
ginnings the motor-truck department of the Tool company 
had grown to such proportions that a separate organization 
became absolutely necessary. The growth was particularly 
marked during the past year. A good staff of active dealers, 
eager to ally themselves with a 25-year old concern, a com- 
plete line of motor-trucks from one to five tons capacity, the 
Duntley gas generator which permits the use of cheap fuels 
such as kerosene and distillate as an exclusive feature, all 
these have helped to build up the prestige of the 'Little Giant' 
truck and to practically double the volume of business dur- 
ing 1917. The factory at Chicago Heights has an amount of 
business on its books that will take months to complete, not- 
withstanding the increased facilities for manufacturing that 
recently have been added. At present, slippery streets, the 
rising cost of horse-flesh and horse-feed, the shortage of labor, 
the unqualified endorsement of motor-trucks by the railroads 
in the present traffic congestion, are factors which induce 
optimism for the motor-truck business. The Little Giant 
Truck Co. is owned and controlled by the Chicago Pneumatic 
Tool Co., and the officers are the same: W. 0. Duntley, presi- 
dent: W. B. Seelig, secretary; L. Beardsley, treasurer; with 
T. J. Hudson, sales manager. The headquarters will remain 
in the Little Giant Bdg., 1615 Michigan Ave., as heretofore. 



FREE INSTRUCTION IN TRACTOR AND 
MOTOR-TRUCK DRIVING 



How to use gas tractors with the greatest efficiency, and 
how to lengthen their lives and increase their usefulness by 
keeping them in perfect repair, such is the object of the 'short 
course' to be given by the University of California at the 
Experiment Station at Riverside from February 11 to 16. The 
University points out that, with the present limited supply of 
labor, it is the patriotic duty of every owner of a tractor to 
see that his tractor does as much work and as good work as 
possible. Proper training for the operator and proper care of 
the machine are of the first importance. This tractor course 
will be similar to one recently held at Davis, where 184 
people learned how to operate and to repair tractors. There 
will be lectures, illustrated with charts and models, on gas- 
engine principles, fuel, carburetors, magnetos, timing, adjust- 
ment, and all details. Instruction is given by experts from 
various factories as to the construction, repair, and operation 
of the eight or more makes of tractors to be used. There will 
be field demonstrations on the operation of tractor-machinery 
and tests of horse-power will be made. Each student will have 
an opportunity for practical work in soldering, pipe-fitting, 
carburetor-adjustment, bearing-adjustment, ignition-timing, 
belt-lacing, and the like. The course is open only to those 
who can show that they will be able to make definite use of 
the knowledge gained. The only expense will be a registra- 
tion fee of one dollar. 



C. P. Coleman was elected president of the Worthinctox 
Pump & Machinery Corporation, at a meeting of the board 
of directors, held on Monday, December 31, 1917. 



Gustave A. Overstrom and Charles V. Craig have made a 
contract for handling the 'Universal' concentrator, covered by 
application for patent, serial number 132,387. Mr. Craig under- 
takes to manufacture and sell the machines, becoming half 
owner of the patent right. 

'Caterpillar Times' for December last, tells of the extraordi- 
nary feats performed by the many types of caterpillar trucks 
and tractors produced by the Holt Manufactubing Co., Inc., 
of Stockton, California. One achievement is plowing up 35 
to 50% grades in the State of Washington. Other machines are 
shown engaged in threshing grain, harvesting beans, logging, 
and doing work in road-building. 

'Standard Oil Bulletin' for December gives praise to Japan 
in a look across the Pacific for commercial expansion; tells 
the story of Tom Orr's Ford car, the oldest active representa- 
tive of this brand in California; a pleasant review of certain 
mascots; and then offers an interesting discussion of viscosity 
of oil and the critical velocity in pipe-line transportation. 
There is also a list of the employees of the Standard Oil in 
California who have joined the colors. 

There was placed in service in December for the Cerro de 
Pasco Mining Co., Peru, a 3000-kw. hydro-electric plant. The 
company -already had one plant of 9000 kw. In December the 
Homestake Mining Co. started, at Spearfish, South Dakota, a 
4000-kw. hydro-electric plant, thus duplicating the former 
plant. Frank G. Baum, consulting engineer of San Francisco, 
had charge of the engineering construction of both the above 
plants, and has under way a 1000-hp. hydro-electric plant for 
the San Luis Mining Co., of Mexico. 

A. Schwarz, consulting engineer, of Joplin, Missouri, has 
just completed an extensively equipped laboratory for physical 
and chemical testing, with a great number of flotation ma- 
chines and all necessary auxiliary apparatus. The ore-testing 
plant is capable of handling one ton of ore, and contains prac- 
tically every ore-crushing and grinding appliance and every 
concentrating machine of importance in use today. There are 
also in course of construction furnaces for all kinds of heat- 
treatment, and an electrolytic department. 

'Duplex Doings, the Heavy Haulers' Magazine, for Decem- 
ber, presents a paper on a new adaptation to trucks consisting 
of a power-windlass, which is of the self-contained single- 
drum type, with a drum 75 in. diam. by 21 in. long, with a 
flange-diameter of 17 in. It is operated by a worm and worm- 
wheel from the transmission by a Whitney roller chain to the 
drum-shaft. The drum is operated by cone-friction, capable of 
handling a load of 10,000 lb. at a 4-in. radius. The rope-speed 
is 50 ft. per minute at an engine speed of 1000 r.p.m. The 
same issue contains articles with illustrations showing trucks 
adapted to house-moving, lumber-hauling, and other uses. 

Don A. Carpenter & Co is in the field with a brand-new 
catalogue for 1918, being issue No. 10. It is a practical list of 
equipment for miners, contractors, quarrymen, irrigation en- 
gineers, and for those in charge of power-plants, pumping- 
stations, and general machine shops. The illustrations and 
descriptions are of the kind that enable the engineer and 
mechanic to definitely select what he requires, and full de- 
tails for ordering are given so as to avoid mistakes. The 
firm is the El Paso agent for the compressors and other equip- 
ment made by the Chicago Pneumatic Tool Co., the pumps 
manufactured by the Goulds Mfg. Co., the Nagle boilers, shop 
equipment of the Canedy Otto Mfg. Co., the Champion Blower 
& Forge Co., and many other leading firms. The catalogue is 
well printed, and well-bound for service; it has useful tables 
and formulae for shop-practice, steam and water engineering, 
and for the use and control of internal combustion engines; 
and is also provided with an excellent index.

TN tliese days of freight congestion it is worth while to 
•*- draw attention to the large amount of useless printed 
matter issued, under an official frank, from Washington. 
For instance, we have been receiving reports from the 
Department of Agriculture and from the Board of Tem- 
perance. In both cases the printed matter went into the 
waste-paper basket, together with much similar stuff, be- 
cause it did not bear remotely upon the subjects coming 
within our purview, as the senders ought to have known. 
And what of the hundreds of tons of piffle sent broad- 
cast over the country by members of Congress? The 
abuse of mailing privileges by our legislators is a national 
scandal, and without humor in this hour of crisis. 



PUBLICATION in a Colombian engineering journal 
*- of an estimate, by Enrique U. Ramirez, of the cost 
of building a railroad from Bogota, the capital city of 
the Republic, to the head of navigation on the river 
Meta, brings to mind the circumstances of our negotia- 
tions with Colombia for the Panama Canal concession. 
President Marroquin demanded a cash payment, insig- 
nificant in comparison with what we paid the French 
company for assets of no great value, and the purpose 
that Marroquin had in view was the construction of this 
very railroad. That would have afforded the great 
Colombian plateau an outlet to the United States and 
Europe with only two transfers in transit against three 
by way of the Magdalena, and with infinitely easier 
gradients and lower costs. We did Colombia a wrong 
at Panama that is keenly felt by our people ; never- 
theless the payment of 'conscience money,' as once was 
proposed, would only deepen the sting. It would be a 
practical thing, however, to finance this needed artery 
of commerce for Colombia and thereby help to develop 
the resources of that country. 



TV7E have read portions of the January bulletin of the 
' * Institute with cynical amusement, on account of the 
frequent emergence, upon the surface of its pages, of 
several commercial controversies regarding the merits 
and demerits of sundry machines. The editor of the 
bulletin, and therefore of the transactions, has our under- 
standing sympathy in his effort to steer a straight course 
among these shoals of trade rivalry. We think that the 
publications committee of the Institute should consider 



seriously the knotty problem of distinguishing between 
technical disputation and trade controversy. We have 
animadverted more than once against the sort of paper 
that is a carefully prepared advertisement, for example, 
"The Smith table' by Smith himself, or 'The Jones classi- 
fier', by the Hon. Jones. The volumes of the transac- 
tions of the Institute include several such trade propa- 
gandas. Now we are treated to violent disputes over the 
efficiency and deficiency of sundry machines. We doubt 
whether such disputes are advantageous to anybody. 
They have no value as technical evidence, because the 
testimony is bitterly partisan, and they are used equally 
to disparage the rival products. If the bulletins and the 
transactions are to echo the advertising pages of the 
trade press, then one rule should be put in force, namely, 
that any member of the Institute expressing an opinion 
on a machine should state his business connection, if any, 
with the manufacture of that machine or of any com- 
peting machine. Some of us may not need this informa- 
tion but the student of technology and the seeker after 
trustworthy information, whether reading the bulletins 
or perusing the same matter in its embalmed form in 
the bound volumes of the transactions, should be given 
this necessary warning. 



{~\N January 14, after two months deliberation, Judge 
" Wolverton of the U. S. District Court at Portland, 
Oregon, handed down his decision on the application for 
a temporary injunction in the case of American Smelting 
& Refining Company v. Bunker Hill & Sullivan Mining 
& Concentrating Company. In substance the Court 
holds that until the trial of the case upon its merits the 
Bunker Hill should continue to ship to the smelting com- 
pany all its product containing more than 30% and less 
than 7.5% lead, but that the Bunker Hill could smelt its 
products outside these limitations or dispose of them as 
it saw fit. As a condition to the granting of the injunc- 
tion, the Court first required a bond in the sum of 
$20,000, which amount has since been increased to 
$250,000. In the course of the opinion the Court sug- 
gests that the Bunker Hill had the right to dispose of 
its high and low-grade products, but that the company 
should not be at liberty to deviate from the custom and 
practice that it had followed in the years immediately 
prior to the controversy. We understand that the inter- 



110 



MINING and Scientific PRESS 



January 26, 1918 



mediate product includes about half the tonnage of lead 
and ore produced by the Bunker Hill. The Court states 
that its opinion is not conclusive, but is a preliminary 
statement for the purpose of determining what should 
be done in advance of a full trial. The opinion is too 
long for publication, but we may mention that the Court 
holds that the Bunker Hill contract was assignable by 
the Tacoma company to the American Smelting com- 
pany, and that the Bunker Hill company apparently 
anticipated such transfer. In referring to the conten- 
tion of the Bunker Hill that the American Smelting 
company had formed a combination with other smelting 
companies to prevent the Bunker Hill from securing a 
market for such of its products as were not covered by 
the fixed terms of the contract, the Court says : "Another 
suggestion is that the American Smelting & Kenning 
Company has brought about an unlawful combination 
with other smelting companies, so that it has a monopoly 
of the market for the purchase of lead ores, and for that 
reason that it ought not to be allowed to prevail here. 
"While there is a surmise that such may be the ease, the 
testimony in the record falls far short of establishing 
the fact." 

TpHE War Minerals Committee has taken the position 
■*- that iron, copper, lead, and zinc are not of practical 
importance as subjects for their consideration, because 
the supply of these metals is reasonably assured. They 
have, however, given special attention to the encourage- 
ment of domestic production of pyrite and manganese. 
To ensure an increase in the output of these materials it 
is essential to guarantee prices for a sufficient period to 
warrant the outlay that would be incurred in developing 
the available deposits. Although spot prices for domestic 
pyrite, for example, range from 25 to 30 cents per unit of 
contained sulphur, the sulphuric-acid makers will not 
quote such figures for future delivery. The result is to 
discourage the opening of new mines. Similarly, offer- 
ings of manganese lead to no transactions unless accom- 
panied with samples and a firm proposition to deliver 
stated quantities ready for prompt shipment. Uncer- 
tainty as to the duration of the War is responsible for 
these limitations, and the only remedy is for the Govern- 
ment to give to possible producers assurance in some 
form of a return that will enable them at least to cover 
their outlay. The Government is furnishing the money 
to enlarge existing acid-plants, and it would, therefore, 
seem logical to foment the output of the requisite raw 
material. Members of the Committee suggested that the 
price might be stabilized for two years. That would 
afford some warrant for development, but it would still 
leave the question of disposal of the product at the Gov- 
ernment price subject to a demand that might fail. This 
aspect of the matter led the Committee, with the approval 
of the War Industries Board, to recommend to the Presi- 
dent that a sum of $5,000,000 be made available by the 
Bureau of Mines for making definite contracts for 18 
months or more for an increased supply of pyrite to be 
delivered to plants, designated by the Government, from 



which it buys its sulphuric acid. This action is con- 
structive and meritorious. Similar aid might be ex- 
tended with propriety to producers of manganese and 
some other needed minerals. 



Mining After the War 



Under present conditions the financing of mining op- 
erations should be made with an expectation of impend- 
ing changes in demand and in corresponding market- 
prices. We limit ourselves necessarily to the speculative 
mining field, without extending the argument to other 
branches of industry. No one will accuse us of pessimism 
in saying this, since we are thereby actually emphasizing 
the optimism of the Government in declining to fix metal 
prices for periods longer than four months. That means, 
primarily, that the Government is not convinced that 
hostilities will be greatly prolonged, in which event it 
would not continue to be a heavy purchaser, in view of 
the fact that its present authority for extraordinary ex- 
penditures is for the duration of the War only. No con- 
tinuance of a general programme of military prepared- 
ness beyond the War has been arranged, and a great pro- 
portion of the Government contracts are on the basis of 
cost plus 10%. Therefore the completion of such con- 
tracts is not obligatory. Stoppage of further outlay may 
be ordered when desired by providing compensation for 
work done to the time of rescinding orders. The United 
States is the virtual purchasing agent for the Allies, and 
their credit in our market at this moment is essentially 
Uncle Sam's credit, since foreign settlements are effected 
through warrants drawn on our National Treasury 
against credits authorized by Congress. It must be noted 
that commercial foreign credits will be practically non- 
existent at the moment of declaring peace, and also for 
some time after a treaty of peace has been signed. The 
peace negotiations will involve so many difficult problems 
that of necessity the sittings of the council will be 
lengthy. An armistice pending these negotiations can- 
not permit continuance of military preparations. The 
market demand for raw material will, accordingly, be 
subjected to conditions for which no provisions have 
been made, and prices, at best" will be ' nominal. ' Trad- 
ing for a time would practically cease. We must be care- 
ful lest we be precipitated from our paradise of high 
prices into a limbus fatuormn. It is our firm belief that 
the Government, having taken upon itself the useful 
function of regulating prices, should also appoint one 
more committee for the purpose of drawing a well-con- 
sidered plan leading to some appropriate legislation for 
protecting industry against the collapse that otherwise 
threatens to ensue as soon as the guns cease firing. Such 
a disaster may not be scorned because it may be only 
temporary. It is well enough to bolster our optimism by 
talk of reconstruction after the War, but it will take 
months to arrive at an acceptable treaty, and more 
months to develop an extensive programme of reconstruc-

imii and i" establish the banking credits on which busi- 
ness may proosed. This will involve a serious cheek upon 

industry, a shortage of work Eor all classes of labor, dis 
oordant prices, financial timidity, and money stringency, 
unless wise provision to bridge that period of uncertainty 
be made in time. Meanwhile the larger mining opera- 
tions are being based on a possible return to pre-War 
prices, at a reduced output, and new ventures should 
be directed in the light of a safe market no further ahead 
than the guarantee of prices by the Government. 

Unto the End 



We are living in days when successive crises fail to 
shock our imagination, just as the frequent recital of 
horrors makes callous our feelings. Nevertheless the 
moment is full of significant events. The pronounce- 
ments of the Premier of Great Britain and the President 
of the United States have been published so nearly to- 
gether as to emphasize the essential solidarity of the two 
English-speaking nations and to hearten their peoples 
with the assurance that the two governments know what 
course they are steering. The War has reached that 
crucial stage when the actual fighting is subordinated to 
political considerations, because the apparent absence of 
a decision on the battlefield is joined to the hardships 
that winter brings upon the warring peoples. The men 
at the front — our gallant defenders in the trenches — do 
not doubt the issue, we do not doubt them, but they are 
asking if the people at home will see it through, if they 
will hold firmly to the end. Signs multiply that the na- 
tions of Europe are weary of fighting, they count their 
losses and ask anxiously 'How long'? Lack of food and 
fuel begins to sap the ardor of the onslaught. This is 
the moment when the quitter falters and the sticker 
stays; in conventional language the morale of some of 
the belligerents appears to be weakening. Shall fright- 
fulness triumph over a blood-soaked world ; shall the out- 
law be conciliated with fresh scraps of paper? France 
lifts a mournful face in which firm resolve gleams un- 
dismayed ; Britain smiles with the set teeth of a bulldog ; 
America raises her hand and shouts, 'We come!' If 
there is to be any quitting, it will not be among these. 
Our leaders have stated our aims — enough of that — it is 
hits that count henceforth. Peace talk, with its poison 
gas of bolshevik anarchy, must await the only conclusion 
that will restore civilization. Germany has seceded from 
civilization. The world cannot remain half-slave and 
half-free. Either this canker of military ruthlessness 
must be cut out or we relapse to a scientific barbarism. 
Are we to be cogs in an infernal machine or citizens each 
in his own democracy, free to live and let live ? It is one 
or the other. The Prussian has not changed the spirit 
of his paranoiac dream, the Pan-German still hopes to 
make good his will to conquer. A few days ago General 
von Lieb in a speech before the German Conservative 
Congress said: "We must recognize only one principle, 
namely, that might is right, and must know neither senti- 



iikii i . nor consideration of humanity, nor compassion. 
We niusi aave Belgium ami northern France. The curse 
of God is upon the French. France must be bled white. 
We must have a strong peace." There speaks the voire 
of the beast with the brains of an engineer, undaunted by 
the world's reprobation, unfeeling for the butchery' he 
has provoked. In every great war there comes a moment 
when the issue seems either doubtful or unsettled; that 
is the moment when moral courage gives a new edge to 
physical bravery. Such a time came after three years 
of the Civil War; such a time came in the Napoleonic 
struggle after the battle of Friedland, when the Allies 
signed the treaty of Tilsit and legalized Napoleon's con- 
quests, thereby committing Europe to eight more years of 
warfare. At Friedland the Russian army was so badly 
beaten that the Czar and the King of Prussia capitulated. 
But England continued to fight Napoleon in Spain and 
on the sea, and by her tenacity of purpose eventually 
rallied the Allies to final victory at Waterloo. France, 
England, the United States, and their allies, mean to 
fight to a sure decision, although it is likely to be brought 
about not by any single battle but by a steady ham- 
mering of the Enemy. We are fighting for peace, for a 
peace that shall endure, not a patched-up truce enabling 
the Enemy to re-organize himself for another spring at 
the throat of civilization. A treaty with an outlaw is a 
scrap of paper. Our aim is to create a league of nations 
committed to the preservation of international order. 
Shall we ever have a league more effective than the one 
now existing among the Allies? If this league cannot 
bring the breaker of the peace to his knees then no 
imaginable combination in the future can do so. Now is 
the chance to prove to the world that predatory mili- 
tarism is a punishable crime, that it is incompatible with 
social progress, and that a majority of civilized nations 
is ready to check it with all the resources of outraged 
humanity. 

The Fuel Order 



On January 17 Mr. H. A. Garfield, the head of the 
U. S. Fuel Administration, issued an order for regu- 
lating the supply of coal throughout the country, for the 
purpose of expediting the shipment of supplies of war 
from our ports to our own army and to the armies of the 
Allies in Europe. In order to accomplish this purpose 
an executive mandate was issued, forbidding the burning 
of fuel by manufacturers east of the Mississippi river, 
except those engaged in a few classes of work connected 
with the War, on January 18 and for four succeeding 
days; also on every Monday from January 28 to March 
25. This order evoked many protests and much verbal 
confusion. Four pronouncements of opinion should be 
noted. Mr. Samuel Gompers, speaking for the American 
Federation of Labor, said that the workers of the Nation 
will be the greatest sufferers from the fuel restriction 
order, but ' ' they will maintain their loyal stand, despite 
the suffering and sacrifices which they may be called 



112 



MINING and Scientific PRESS 



January 26, 1918 



upon to bear." The War Service Executive Committee 
of the Chamber of Commerce of the United States issued 
a statement criticizing the order, but announcing that, 
since it had been issued, "it is clearly the duty of busi- 
ness men to do all in their power to carry out its spirit 
and purpose." Mr. Elbert H. Gary declared on be- 
half of the United States Steel Corporation : ' ' "We prob- 
ably shall not pay the wages of our men when they are 
not actually employed. To do so would be contrary to 
the custom of the trade, and would establish a precedent 
which eventually would be unfair to the employer as well 
as to the employee." At the close of an explanation 
issued by Mr. Garfield himself, he said: "This is War! 
Whatever the cost, we must pay, so that, in the face of 
the enemy, there can never be the reproach that we held 
back from doing our full share. Those ships laden with 
our supplies of food for man, and food for guns, must 
have coal and put to sea." These four statements will, 
we believe, reflect the opinion of the intelligent portion 
of the public. The existing shortage of fuel does not rep- 
resent inability to move the quantity normally consumed. 
On the contrary, more coal has been delivered by the 
railroads during the year 1917 than ever before in the 
history of the country. The Geological Survey estimates 
that the output of the mines was approximately 50,000,- 
000 tons greater than in 1916, and in that year the record 
of previous production was broken. The National City 
Bank of New York is responsible for the statement that 
practically no stocks of coal exist outside consumers' 
hands. The evidence clearly indicates that two factors 
have produced the unusual situation that the Govern- 
ment undertook to meet by a suspension of manufactur- 
ing. These factors are, first, increased fuel consumption 
resulting from the intensive production of supplies for 
War, in addition to those needed for domestic use, and, 
second, the inadequacy of transportation facilities to 
cope with the vastly augmented tonnage of coal neces- 
sitated under these unusual conditions. The difficulty 
has been aggravated by an exceptionally severe winter, 
involving a suddenly enlarged demand for household 
purposes, at a moment when the railroads were further 
crippled by snow-blockades and the many impediments 
to operation that follow from excessively low tempera- 
tures. Mr. William M. Calder, in the Senate, called at- 
tention to the fact that the Fuel Administration had in- 
terdicted the buying of coal during the summer season, 
declaring at that time that the shortage was psycho- 
logical rather than real, and that the accumulation of 
such supplies for household or other requirements would 
be deemed hoarding. It will be remembered that the 
failure of the railroads to handle successfully the grow- 
ing volume of freight was the subject of a special report 
by the Federal Trade Commission presented to Congress 
as far back as June of last year, coupled with a definite 
recommendation for Government control of the transpor- 
tation systems. The inevitable conclusion from all the 
facts is that there has not been proper co-ordination of 
the governmental departments, bureaus, and committees 



that are responsible for the practical work of directing 
the activities of the country. In consequence of this 
lack of co-ordination the welfare of the people and our 
preparation ior the business of War have suffered. This 
criticism has been repeated frequently by many sincere 
and earnest patriots on the floor of Congress and in the 
press, but it has gone unheeded. In the storm of Con- 
gressional debate provoked by Mr. Garfield's order a 
number of Senators accorded the President the warmest 
praise for untiring devotion to his overwhelming duties, 
but they reminded him that he was attempting the im- 
possible in personally struggling with such multitudinous 
details as the present administrative organization forced 
upon him. It is manifestly beyond the power of a single 
individual to harmonize the efforts of the numerous 
branches into which the executive authority of the Gov- 
ernment has been subdivided to meet the exigencies of 
the hour. This had been so fully realized by Congress 
that bills were drafted by the Military Committee of the 
Senate just before the emergency fuel order was issued, 
providing for the appointment of a director of war in- 
dustries, and for a non-partisan war cabinet of three 
members to stand between the President and the usual 
cabinet, the duty of which extraordinary council shall 
be specifically to co-ordinate the work now being per- 
formed by the several departments and special commit- 
tees. It is fortunate that these bills were drawn before 
the flood of protest evoked by Mr. Garfield's action. 
Thus no sting of criticism is involved in them, and the 
President can accept the measures, if passed, in the spirit 
of constructive aid that prompted those who framed 
them. The country will also feel an added confidence in 
the conduct of the nation's affairs. No one can ignore 
the fact that popular confidence was rudely shaken by 
the drastic action that was taken to remedy the fuel short- 
age. It was a difficulty that apparently could have been 
avoided by greater foresight. Better organization will 
be needed now to assure a cordial settlement of the 
difficulties likely to arise from the temporary stoppage 
of so many industries. Heavy losses are sure to result, 
and it is plain that the burden will not fall equally upon 
those affected. Manufacturers operating on the basis of 
cost plus 10% can evidently pay their workmen during 
the period of idleness, charging the amount in their costs, 
while those operating independently would suffer with- 
out remedy. Already we see that prominent business 
men reject the plea to continue the payment of wages as 
a patriotic duty. No provision for compensation has 
been made by the Government, and if money is withheld 
from the laborers the consequent distress will necessitate 
instant relief, together with ample assurance against the 
recurrence of such painful incidents. That the action 
taken by Mr. Garfield was imperative under the existing 
circumstances will be accepted by the people with good 
grace, but those circumstances should not have been 
allowed to arise, and it is the duty of those in authority 
to grapple more firmly with the problems arising from 
the extraordinary conditions of war.

The Domestic Production of Chrome 

The Editor: 

Sir — the war meeting of the New York Section of the 
American Institute of Mining Engineers (sitting in joint 
session with the American Electro-Chemical Society in 
conjunction with the third National Exposition of Chem- 
ical Industries) was held to discuss the supply of raw 
materials for the manufacture of ferro-alloys. Chrome 
received the principal consideration. 

The domestic production being only 47,035 tons as 
against an importation in 1916 of 115,945 tons, the ques- 
tion was raised as to how much could the United States 
supply from its own mines? Attention was also called 
to the apparent exhaustion of the known deposits. 

No doubt there is plenty of chrome available in New 
Caledonia and Rhodesia, but to obtain this ore it becomes 
necessary for the United States to send ships that are at 
present needed to transport food to the Allies. If neces- 
sary we can, of course, do this, but is it an act of patri- 
otism for our industries to compel our Government to 
import this ore without making a greater effort to develop 
our own deposits? I believe there is little question in the 
minds of the Western miners that if it were necessary the 
United States, with Alaska, could produce all the chrome 
ore demanded for the manufacture of munitions. There 
is, however, good reason for doubt, because, if the present 
policy on the part of our buyers is maintained, there will 
be considerably less offered in the future than is at pres- 
ent available. I refer to the secretive and non-cooper- 
ative policy maintained by the consumers of chrome ore 
in their effort to keep down the price of this raw material. 
I believe it is a mistaken and short-sighted policy on the 
part of the consumers not to offer more encouragement 
to domestic production, especially at a time when ocean- 
going space is in such demand. 

It has been said that a rise in the price of this ore 
would not materially increase the production. I submit 
figures herewith showing the enormous increase in the 
production of this ore in the United States within the 
last five years due to the slight increase in price. 

Production of Chrome Ore 

Year Tons Price per ton 

1913 255 $11.19 

1914 591 14.75 

1915 3,281 14.85 

1916 47,035 35.00 

1917 4S.000 40.00 

In order for us to consider thoroughly the question of 
how much the United States will produce it is necessary 



to investigate both the physical features surrounding the 
occurrence of chrome ore, and also the economic question 
under which these ores have to be marketed. 

Chrome is widely disseminated throughout the Pacific 
Coast states; it is found in more than one-third of the 
counties of California, which alone produced more than 
40,000 tons in 1916, or more than one-third of the total 
imports into the United States for that year. Chromite 
occurs in workable quantities in Oregon, Washington, 
and Alaska. These regions have been but little pros- 
pected for chrome and they will not be prospected until 
such time as the practical miner learns of the market 
value of such ore. 

The consumers may send out all the expert mining men 
they wish to work these deposits but they are not going to 
develop a source of supply for a mineral hitherto con- 
sidered worthless until they educate the practical miner, 
the prospector, and the farmer as to the value of it. They 
are not interested in chromite and unless an incentive is 
given they are not going to become interested; for that 
reason I am strongly of the impression that it would do 
much to stimulate the discovery and the opening of new 
deposits if more assistance and co-operation were given 
to the small producer, especially regarding publicity as 
to the true market- value of the various grades of chromite 
instead of making it as difficult as possible for him to 
ascertain the real value of his ore. He not only should 
know the value of a particular ore, but he should be able 
to ascertain the relative value of the different grades of 
ore arid concentrate. There are many deposits of this 
ore slightly below the grade required by the consumer 
that, by simply crushing and concentrating, would fur- 
nish a high-grade chemical ore. 

Chromite orebodies as a rule occur in relatively small 
deposits. J. S. Diller of the U. S. Geological Survey says 
the largest orebody yet mined on the Pacific Coast con- 
tained about 15,000 tons. Most chrome deposits are 
formed as a crystallization or segregation, during the 
process of cooling, of the chromite contained in molten 
igneous masses, and for that reason the mining of these 
orebodies is uncertain. There are many places where the 
mining of these pockety deposits, although not sufficiently 
attractive to pay for the operation and overhead expenses 
of a company, might be undertaken by the individual 
miner. 

Although the buyers have succeeded in keeping the 
price of the raw chrome down within narrow limits, such 
a policy of secrecy is not to the welfare of the industry, 
and it certainly does not develop mines for production of 



114

raw materials. Rather than the present policy of mys- 
tery, the producers should be made acquainted not only 
with the technical part of its production but also with 
the uses to which it is put. Although most of the writers 
upon the subject of chromite refer to its application in 
the refractory-brick business they present no figures 
showing the consumption of chrome in the steel in- 
dustries, and the producer is left in the dark as to the 
use made of his ore and regarding the future demand. 

As a rule, all that the miner or prospector wants is a 
sufficient return to permit him to do more mining, and if, 
perchance, he does make a profit in the mining of a few 
hundred tons of ore, he is more than likely to re-invest his 
funds in the search for additional deposits. A more 
liberal and frank policy practised by the industrial com- 
panies purchasing the raw ore would not only stimulate 
development, with the possibility of additional orebodies 
being found in the districts at present becoming depleted, 
but it would be cause for the investigation of the chrome 
fields at present unexplored in Washington, Oregon, and 
Alaska.

Excess-Profit Tax for Mines 

The Editor: 

Sir — The proposal of Albert Burch, quoted in your 
editorial of January 12, as modified in the same editorial, 
comes near being a satisfactory solution without, I think, 
quite reaching it. 

The problem is to secure for the State a large, but 
equitably distributed, share of the profits arising from 
increment in value of mining products, due to the War, 
without discouraging production from any source. It 
is in this direction that I think Mr. Burch 's proposal 
fails. It is of the greatest importance to increase pro- 
duction, both because the metals are required for the 
effective prosecution of the War, and also because pro- 
duction tends to keep down prices. We need the produc- 
tion even if it is unprofitable or inadequately profitable; 
and the high-cost mine may furnish just that extra 
margin of product which may save us from runaway 
markets or actual shortage. 

To secure both ends, the increment of price which 
should regulate the rate of taxation should be only that 
in excess of 50% above the average pre-war price (50% 
representing the estimated increase in costs, due to the 
War). The tax should, however, be assessed only on the 
profit actually made, not on the excess value of the prod- 
ucts marketed. This will, of course, result in stimulat- 
ing production from some mines which will have to close 
down after the War ; but it is exactly this production 
that we need now. If we do not obtain it, sooner or later 
we may either risk failure on account of scarcity of 
essential metals, or be compelled to produce them at the 
expense of the State. 

I would therefore re-state Mr. Burch 's formula as 
follows : 



In the ease of mines, oil-wells, and gas-wells, the in- 
crease in the average price received at place of sale for 
each unit of product (that is, each ounce, pound, ton, 
barrel, or cubic foot, as the case may be) for the taxable 
year, over the average price at which the same unit was 
or could have been sold at the same place during the 
pre-war period, shall be ascertained ; and the percentage 
of such increase beyond 50% shall be used as the basis 
on which the excess-profit tax shall be computed. The 
said tax shall consist of not less than 20% and not more 
than 80% of the entire profit for the taxable year. 
Whenever the percentage of increase of price of product 
as aforesaid shall exceed 50% the tax shall be 20% of 
the profit for the year, and whenever the percentage of 
increase of price of product shall be 200% the tax shall 
be 80% of the profit for the year; intermediate rates of 
increase of price of product fixing the war excess-profit 
tax at proportionately intermediate percentage of the 
annual profit. 

This proposal would contemplate allowance for deple- 
tion, etc., remaining on the same footing as under the 
present law.

Food Saving 

The Editor : 

Sir — Since last July we have been very busy re-build- 
ing, after our fire, and making new trials, as we have 
changed the location of our buildings. I had no chance 
to read the Press until a month ago, when I picked up 
what magazines I had left from the fire and saw the 
Hoover 'ad,' and here it is signed and returned to you, 
as requested. I am chef de cuisine and food economist, 
so it will be my good fortune to help the cause a little. 
Wheat flour has gone up 100% since the beginning of the 
War, yet we pay less by $2 to $3 per barrel in Elk City 
than we paid for it 10 years ago ; the parcels-post reduced 
our price here. From necessity of high prices, and the 
little work to be had, I evolved a wheat bread that is 
from 25 to 40% camouflage, a bread that tastes as fine as 
any Vienna roll ever did, and, according to Mr. Hoover's 
precepts. I am now saving from 25 to 40% wheat on 
every loaf I bake, although I have not a wheatless meal 
a week. Stale bread, pieces or whole bread, will make so 
many excellent dishes that there is no reason whatever for 
a single piece of bread, no matter how dry, to he wasted. 
The savings to he made by Mr. Hoover's plan will be 
enormous, unbelievably so ; and the health of the nation 
will increase 100%. Let us all be Hooverized, volun- 
tarily or by force.

Ajo Copper Mine— I 



By COURTENAY DE KALB 



At the town of Ajo, in the western end of Pima county, 
Arizona, is a copper mine now recognized among the 
great ones of the world. It is heing worked by steam- 
shovels, and the ore is leached with sulphuric acid, after 
being crushed to I inch. The monthly shipments of cop- 
per exceed three million pounds. The property is not yet 
completely developed, but 61,000,000 tons of ore aver- 
aging 1.51% copper has been definitely proved. This 
notable addition to the nation's available supply of that 
metal must be credited primarily to the courageous initi- 
ative and unflinching confidence of John C. Greenway. 
He was not alone in his conviction that Ajo would de- 
velop into a premier mine, for he was sustained by the 
mature judgment of L. D. Ricketts ; but the least weaken- 
ing of his own faith in the enterprise during the earlier 
period of development might have led to its abandon- 
ment. The degree of courage required may be inferred 
from the fact that Ajo labored under the burden of a 
history of successive condemnations by men of large ex- 
perience in 'porphyry' mines. These were men who knew 
the characteristics of disseminated deposits ; who under- 
stood the criteria of secondary enrichment ; and they had 
even made tests by rather extensive drilling. In the end 
they withdrew, and nothing is more difficult than to 
resuscitate a mining district that has been investigated 
by competent engineers, supported by abundant capital, 
and then deserted as worthless. Moreover, Capt. Green- 
way, now major of engineers in France, whose military 
title was won as a Rough Rider in the Cuban campaign, 
faced a technical staff that was distinctly cold toward the 
Ajo mines. The first reports were not flatly condemna- 
tory, but an adverse argument was involved in the faint 
praise given. He, however, was ambitious to sponsor a 
great disseminated copper property, and the features 
that had drawn his predecessors to look curiously at Ajo 
encouraged him to take the rather doubtful chances of 



success admitted by his advisers. In the end it proved 
that the earlier drilling had narrowly missed the im- 
portant orebody, and that the expected enrichment did 
not exist, for the Ajo deposit has not been secondarily 
enriched. It consists of an upper zone of copper carbon- 
ate and a lower zone containing primary chalcopyrite 
and bornite. The difference in the copper content be- 
tween the two is only 0.04%, with the higher proportion 
in favor of the carbonate. Acid leaching had been pre- 
vented by abundant caleite formed during a period of 
alteration that preceded the introduction of the copper, 
and sericite is so nearly absent that it can be detected 
only to a small extent by examination with the petro- 
graphic microscope. Thus it is evident that the Ajo de- 
posit presents no analogies to the secondarily enriched 
'porphyries' from which previous experience in dissem- 
inated copper ores had been gained. It was distinctly 
sui generis. 

Part of the early history of Ajo has been given by Ira 
B. Joralemon.* He notes that, next to Santa Rita, New 
Mexico, it is the oldest centre of copper production in the 
South- West. Mr. Joralemon credits the first operation to 
the early 'sixties, but in reality the work began in 1855, 
and in the following year a shipment of high-grade ore 
was made to San Francisco by the Arizona Mining & 
Trading Co. This was a sort of company of gentlemen 
adventurers, organized in the spirit of true pioneering, 
with no more substantial objective than infinite hope in 
the possibilities of an unexplored country. The organ- 
izers were Major B. Allen, J. D. Wilson, William Bland- 
ing, A. S. Wright, and others resident at Los Angeles. 
An expedition was outfitted in that city in 1854, under 
the charge of E. E. Dunbar. It consisted of 20 men, 
among whom were F. Ronstadt, P. Brady, G. Kibbers,

George Williams, Joe Yaney, Charles Hayward, and a 
Dr. Webster. They went first to Yuma, where the expedi- 
tion was divided, one party, caught by the lure of a lost 
mine, plunging into the wilderness in quest of the ever 
elusive Planchas de Plata vein, while the other, follow- 
ing the trail to Tinaja Alta, heard of the Ajo copper 
mines 90 miles east-southeast from Yuma. They found 
these mines to be real, and soon established themselves 
in possession; but mining in Arizona in 1854 required 
familiarity with arms as well as with the pick. The new 
international line, as described in the treaty for the 
Gadsden Purchase, was still undetermined by survey, 
so the Mexican authorities undertook to wrest the mines 
away from the Americans, but they were defeated by 
effective resistance organized by Hayward. The first ores 
shipped came from excessively rich narrow deposits of 
cuprite and native copper, found near the contact be- 
tween the intrusive monzonite and the older rhyolite, 
near the western end of the present workings of the New 
Cornelia Copper Co. Subsequently, rich narrow veins of 
chalcopyrite and chalcocite in the rhyolite were the source 
of ore that kept the district feebly and intermittently 
active for half a century. For a time the ore was hauled 
in ox-carts 400 miles across the desert to San Diego, and 
later it was taken to Yuma, to be floated down the Colo- 
rado river in barges to the head of the Gulf of California. 
Prom this point it was shipped to Swansea. The second 
period began about 1900, when a series of fiascos followed 
the attempts made by numerous companies to exploit 
the small rich deposits in the outlying region around the 
great mass of low-grade ore. Stamp-mills were erected, 
and patent processes for reducing and refining the copper 
were tried, among these being efforts to leach the ores 
with hydrofluoric acid. In 1909 a fresh venture was 
made, and this time by responsible people. The original 
New Cornelia Copper Co., one of the moribund concerns 
of the stock-promoting epoch, was taken under option by 
the General Development Co., and the holdings of the 
Rendall Ore Reduction Co. also were tested by a group 
of capitalists advised by Seeley W. Mudd. After a brief 
campaign of drilling both options were abandoned, but 
in 1911 Capt. Greenway took an option on the New 
Cornelia property for the Calumet & Arizona Mining Co. 
Instead of testing the low-lying areas around Copper 
mountain he directed his attention to the rugged group 
of hills that has proved to be the centre of mineraliza- 
tion. Mr. Joralemon describes these hills as being 
"highly stained outcrops." Whatever may have been 
the character of the central zone through which since 
then the steam-shovels have made a deep wide open-cut, 
the remainder of the area of 55 acres is surprisingly desti- 
tute of green coloration, except where broken in the course 
of exploratory work. The outcrop, however, is clearly 
marked; it consists of a number of low, barren, rocky 
hills surrounded by high peaks and ridges of gray granite 
and rhyolite. The prevailing tint of the encircling moun- 
tains might be described as pale grayish lavender. The 
copper terrain is distinguished by a warm russet hue, 
indicating an excess of iron. The form of the mineralized 



hills is rounded, but the bare rocks have a short angular 
fracture, and are encrusted with the desert glaze. Here 
and there a bit of copper carbonate appears, and a dark- 
green stain is not uncommon on sheltered faces of the 
rougher and larger blocks. A surprise comes, however, 
on breaking the rock with a hammer. No matter where 
one strikes it the stain of copper carbonate is revealed. 
It reaches up to the very crust of brown glaze that had 
obscured it ; through every seam opened by the hammer, 
the green film penetrates. On breaking a few inches 
deeper the feldspars of the monzonite display a pale 
greenish tinge, and this minute coloration proves to be 
leachable, even without reducing the rock to a fine state 
of subdivision. Looking at the walls in the open-cut, as 
they are blasted down to feed the steam-shovels at their 
feet, the appearance is not that of ore but of rock merely 
permeated with greenish tints; and one recalls the com- 
mon joke about a mountain stained with a copper cent. 
It seems, in fact, like mining a stain and making it pay. 
Prom this it must not be concluded that the ore is want- 
ing in signs of richness. As finally broken ready for 
loading by the steam-shovel, the color of a pile of ore is 
dirty greenish gray, but on large blocks the seam-deposits 
are often thick and exceedingly brilliant in color. Tur- 
quoise-blue to verdigris-green are the prevailing shades. 
In places the incrustations are no more than a film, but 
more generally they constitute, a scale of copper mineral 
that can be stripped with a knife, and many seams are 
found as much as an inch thick. This is in accord with 
the habit of the deposit. In monzonites that have not 
undergone profound alteration, such as sericitization or 
chloritization, the jointing developed in the final set of 
the rock is generally irregular; mineralization by sul- 
pliidi s follows the joint-planes, and, to a less extent, de- 
pending upon the degree of compression of the mineraliz- 
ing gases, the sulphides invade the body of the rock, re- 
placing primarily the ferro-magnesian minerals. This 
order is observed frequently, and it is seen in the Ajo 
deposit. The most striking feature to the eye, on exam- 
ining the sulphide ore from the lower unoxidized zone, 
is the abundant deposition of the sulphides, both chalco- 
pyrite and bornite, on seams and joint-planes. They 
form crusts and patches as well as crystalline flakes 
scattered quite regularly over the surface. Narrow vein- 
lets of bornite and chalcopyrite suggest replacement of 
seams of segregated basic minerals, these being tightly 
coherent to the body of the rock, showing quartz often 
developed as prisms protruding into vugs. Cuprite oc- 
curs in the oxidized zone in the same manner; in fact, 
most of the recognizable cuprite is in veinlets cemented 
into the monzonite ; some of the masses of cuprite would 
weigh a pound or more. Cuprite is also seen in such 
veinlets in the sulphide zone, where it is well crystallized. 
and of a dark color, but easily recognizable by the splint- 
ers that flash ruby-red by transmitted light. The copper 
sulphide is disseminated also, and appears to exist mainly 
as bornite. In the process of mineralization the volume 
removed has generally been in excess of that deposited, 
leaving the rock with a rough and minutely pitted sur-

face ; this is a feature observed in other examples of min- 
eralized monzonite. Chlorite is general as a secondary 
mineral, having resulted from the alteration of biotite 
chiefly. Some siderite is also found ; it is secondary, but 
is not always conclusively a product of the period of oxi- 
dation during which the copper was converted to carbon- 
ate. Much magnetite is present, and this, as well as spec- 
ularite, is found with the ore, the specularite appearing 
most commonly on seams and joint-planes. Apatite is 
also abundant, but not to be detected in examination of 
specimens with a hand-lens. The phosphorus appears 
regularly as a constituent of the solutions in circulation 
through the leaching-plant, as shown by analyses of 
weekly composite samples, which contain from 0.162 to 
0.184% of phosphoric acid. At times the solution holds 
0.3% P 2 5 . The chlorine in the solutions is from 0.01 to 
0.008%, and this, plus the chlorine deposited in the 
cathode copper, is fully accounted for by the chlorine in 
the water used for leaching, which carries 0.015%. The 
ore shows no chlorine whatever, hence the phosphorus is 
assumed to be present in the form of the fluo-apatite. 
Thi scarcity of sericite has already been noted, though it 
appears scattered rather abundantly through the miner- 
alized rhyolite at the south-west end of the monzonite 
orebody. 

The structural features of the deposit have been lucidly 
set forth by Mr. Joralemon,t who interprets the known 
relations of the monzonite as indicating a laccolith, over 
which the rhyolite is domed. Drill-testing, still in pro- 
gress on the south-west side of the outcrop, beyond the 
point where the rhyolite is first seen shouldering over 
the monzonite, has penetrated to a depth of 1100 ft. and 
has not yet reached the monzonite. The drill-core, how- 
ever, shows a great deal of native copper, so that it is 
apparently approaching near the zone of mineralization. 
This indicates, also, that the dip of the contact between 
the two rocks is becoming steeper. Whatever additional 
light this may throw upon the relation of the monzonite 
to the overlying rocks, it does indicate at least an ap- 
proach toward its southern limit. Mr. Joralemon states 
that the monzonite laccolith, or 'batholith', which lifted 
the earlier rhyolite beds, is 10 miles long and of irregular 
width, varying from 1 to 4 miles, the direction of its 
major axis being N. 20° W. Toward the north the mon- 
zonite constitutes a series of high precipitous ridges, and 
in this portion of the exposure the facies is quite gener- 
ally that of a coarse grano-diorite, with biotite promi- 
nently developed. Phases of more distinctly dioritic seg- 
regations are common, and Mr. Joralemon calls special 
attention to the fact that "diorite or diabase dikes cut 
both monzonite and rhyolite, but apparently have had 
no important effect on structure or mineralization." 
They are apparently complementary to the monzonite, 
thus accounting for the absence of secondary effects upon 
the parent magma. The dikes, however, have been pyri- 
tized, and their outcrops are very ruddy; the later 
fracturing through the monzonite, to which is ascribed 

tl/oc. cit. supra. 



the opening of avenues for the invasion of the mineral- 
izing agents, is also seen following the dikes, and these 
narrow brecciated and faulted zones, even at a consider- 
able distance from the orebody, display epidotization, 
with accompanying calcite and secondary silica, both in 
seams and throughout the body of the adjacent rock, 
while sulphides of copper and larger amounts of pyrite 
are in evidence. Many of these subsidiary veins through- 
out the otherwise 'dry' monzonite area have been ex- 
plored by prospect-shafts. The monzonite is generally 
gray and hard, in which case considerable hornblende is 
usually present, but in other places it weathers to coarse, 
rough, granular particles, and is then highly stained with 
iron oxide. This is particularly noticeable on the north
